Expose panel mode from kernel to SDM with SDE connector property
CONNECTOR_PROP_MODE_INFO and set panel mode from SDM to kernel
with SDE connector property CONNECTOR_PROP_SET_PANEL_MODE for
avoiding private change in upstream code in QGKI kernel.

Move away from the private and private_flags fields from drm_mode,
as it is being deprecated in latest kernel version. Instead, Add
msm_display_mode as a wrapper to be used in downstream to store these
parameters. Also, store msm_mode in connector_state to be accessed
in commit path.

This change moves the backlight update operation from
drm bridge enable to connector post kickoff.
When timing engine is enabled with programmable fetch
enabled, the timing engine will start counting from
the prog_fetch_start point (which is somewhere in VFP).
It’s a grey area from that point to the actual panel
vsync and SW should not trigger DMA command during that
time.
During display resume, sometimes the INTF timing engine
do not get enabled completely at the first vblank irq.
The backlight update cmd transfer trigger as part of the
drm bridge enable can also take place at the same time,
that may cause DSI cmd transfer failure.

Currently, in SST mode, sink edid is read once after hpd
and reused on subsequent mode enumeration calls. But in
MST mode, there is no caching and the driver re-reads the
edid from the sink on every get_modes call for each monitor.
Each read takes more than 500ms causing unnecessary delays
during MST enumeration.
This change reads the edid once per hpd and uses the
cached data on subsequent calls.

The change adds a new mode property allowed_mode_switch. The new
property is a 32bit bitmask that indicates the modes each mode
can switch to. This change is required to pass the driver mode
switching capabilities, so that user mode can reject any mode switch
that is not supported by the driver.

When DRM property objects are created, the DRM framework attaches a
dellocator which can eventually free the object when the last reference
is removed from it. The framework can only do this before the driver is
registered. If a property is created after the registration then the
framework is unable to attach a deallocator causing a memory leak during
tear down.
The current DP driver creates a new colorspace property whenever a
new dp connector is initialized. It creates a base connector at probe
time prior to registration. But then it also creates new connectors,
post registration, whenever a new MST dongle is attached to the
topology, causing memory leaks.
This change limits the property creation to the base connector and
attaches the same object to MST connectors to avoid memory leak.

This change implements a new feature to read the cmds response
of the panel from sde connector interface. Sde connector opens
debugfs interface for all the connectors those have support for
cmd receive operation.
Sde connector init module creates rx_cmd debugfs file at
/<debugfs-root>/dri/0/DSI-1/ for DSI-1 connector.
Format for DSI command transfer:
echo "command bytes" > /<debugfs-root/dri/0/DSI-1/rx_cmd
byte-0: the length of received buffer
byte-1: data-type
byte-2: last command. always 0x01
byte-3: channel number
byte-4: flags. MIPI_DSI_MSG_*, must be set to 0xa
byte-5: 0x00
byte-6 and byte-7: command payload length
byte-8 to byte-[8+payload length]: command payload
Example:
echo "0x01 0x06 0x01 0x00 0x0a 0x00 0x00 0x01 0x0a" > rx_cmd
The command receive operations are allowed only if controller
(ex. DSI controller) is in active state.
Read the value of panel response:
cat /<debugfs-root>/dri/0/DSI-1/rx_cmd
returns the value of this command.
nothing - failure, xx xx - success.
