devlink: add the ability to update device flash
This series is the second step to allow trouble shooting and recovering
devices in bad state without the use of netdevs as handles. We can
already query FW versions over devlink, now we add the ability to update
the FW. This will allow drivers to implement some from of "limp-mode"
where the device can't really be used for networking and hence has no
netdev, but we can interrogate it over devlink and fix the broken FW.
Small but nice advantage of devlink is that it only holds the devlink
instance lock during flashing, unlike ethtool which holds rtnl_lock().

Add devlink flash update command. Advanced NICs have firmware
stored in flash and often cryptographically secured. Updating
that flash is handled by management firmware. Ethtool has a
flash update command which served us well, however, it has two
shortcomings:
- it takes rtnl_lock unnecessarily - really flash update has
nothing to do with networking, so using a networking device
as a handle is suboptimal, which leads us to the second one:
- it requires a functioning netdev - in case device enters an
error state and can't spawn a netdev (e.g. communication
with the device fails) there is no netdev to use as a handle
for flashing.
Devlink already has the ability to report the firmware versions,
now with the ability to update the firmware/flash we will be
able to recover devices in bad state.
To enable updates of sub-components of the FW allow passing
component name. This name should correspond to one of the
versions reported in devlink info.
v1: - replace target id with component name (Jiri).

Since commit d6cd33ad71 ("regulator: gpio: Convert to use descriptors")
the GPIO regulator had inverted the polarity of the control GPIO. This
problem manifested itself on systems with DT containing the following
description (snippet from salvator-common.dtsi):
gpios = <&gpio5 1 GPIO_ACTIVE_HIGH>;
gpios-states = <1>;
states = <3300000 1
1800000 0>;
Prior to the aforementioned commit, the gpio-regulator code used
gpio_request_array() to claim the GPIO(s) specified in the "gpios"
DT node, while the commit changed that to devm_gpiod_get_index().
The legacy gpio_request_array() calls gpio_request_one() and then
gpiod_request(), which parses the DT flags of the "gpios" node and
populates the GPIO descriptor flags field accordingly.
The new devm_gpiod_get_index() calls gpiod_get_index(), then
of_find_gpio(), of_get_named_gpiod_flags() with flags != NULL,
and then of_gpio_flags_quirks(). Since commit a603a2b8d8
("gpio: of: Add special quirk to parse regulator flags"),
of_gpio_flags_quirks() contains a quirk for regulator-gpio
which was never triggered by the legacy gpio_request_array()
code path, but is triggered by devm_gpiod_get_index() code
path.
This quirk checks whether a GPIO is associated with a fixed
or gpio-regulator and if so, checks two additional conditions.
First, whether such GPIO is active-low, and if so, ignores the
active-low flag. Second, whether the regulator DT node does
have an "enable-active-high" property and if the property is
NOT present, sets the GPIO flags as active-low.
The second check triggers a problem, since it is applied to all
GPIOs associated with a gpio-regulator, rather than only on the
"enable" GPIOs, as the old code did. This changes the way the
gpio-regulator interprets the DT description of the control
GPIOs.
The old code using gpio_request_array() explicitly parsed the
"enable-active-high" DT property and only applied it to the
GPIOs described in the "enable-gpios" DT node, and only if
those were present.
This patch fixes the quirk code by only applying the quirk
to "enable-gpios", thus restoring the old behavior.

Add support for the RTC's NVRAM using the standard nvmem support that is
part of the Linux RTC framework.
This driver already has a sysfs attribute that provides access to the
RTC's NVRAM as a single 16-bit value. Some chips have more than two
bytes of NVRAM, so this will not work for them. It's also non-standard.
This sysfs attribute is left in for backward compatibility, but will only
be able to read the first two bytes of NVRAM. The nvmem interface will
allow access to all NVRAM, e.g. eight bytes on the isl1218.

While we can only truncate a block under the page lock for the current
page, there is no high-level synchronization for moving extents from the
COW to the data fork. This means that for example we can have another
thread doing a direct I/O completion that moves extents from the COW to
the data fork race with writeback. While this race is very hard to hit
the always_cow seems to reproduce it reasonably well, and it also exists
without that. Because of that there is a chance that a delalloc
conversion for the COW fork might not find any extents to convert. In
that case we should retry the whole block lookup and now find the blocks
in the data fork.
