We face the issue that link change interrupt and link status may be
reported by different PHY layers. As a result the link change
interrupt may occur before the link status changes.
Export phy_queue_state_machine to allow PHY drivers to specify a
delay between link status change interrupt and link status check.

The phylib interrupt handler handles link change events only currently.
However PHY drivers may want to use other interrupt sources too,
e.g. to report temperature monitoring events. Therefore add a callback
to struct phy_driver allowing PHY drivers to implement a custom
interrupt handler.

This patch is a step towards allowing PHY drivers to handle more
interrupt sources than just link change. E.g. several PHY's have
built-in temperature monitoring and can raise an interrupt if a
temperature threshold is exceeded. We may be interested in such
interrupts also if the phylib state machine isn't started.
Therefore move enabling interrupts to phy_request_interrupt().

This patch is a further step towards decoupling firmware handling from
the actual driver code. Firmware can be for PHY and/or MAC, and two
pairs of read/write functions are needed for handling PHY firmware and
MAC firmware respectively. Pass these functions via struct rtl_fw and
avoid the ugly switching of mdio_ops behind the back of rtl_writephy().

The driver core first registers with the hwmon and thermal subsystems
and only then proceeds to initialize the switch driver (e.g.,
mlxsw_spectrum). It is only during the last stage that the current
firmware version is validated and a newer one flashed, if necessary.
The above means that if a new firmware feature is utilized by the
hwmon/thermal code, the driver will not be able to load.
Solve this by re-ordering initializing the switch driver before
registering with the hwmon and thermal subsystems.
