The SFC9000-family controllers have firmware to manage all board
peripherals including temperature, heat sink continuity and voltage
sensors. The firmware reports sensor alarms, which we log, and
will shut down the board if necessary.
Some users may want to monitor their boards more closely, so add an
hwmon driver that exposes all sensors reported by the firmware. Move
efx_mcdi_sensor_event() into the new file so it can share the array of
sensor labels with the hwmon driver.

These are defined alongside the firmware protocol in mcdi_pcol.h.

When the MC reboots, either as part of a firmware upgrade or due to a
bug, it attempts to complete (with an error) any requests that were
outstanding before the reboot. Since there is an inherent race
condition in checking this, it will also write to a status word in
shared memory.
If we look at each of these separately, we may detect each reboot
twice, resulting in a spurious command failure after a firmware
upgrade or frustrating recovery from a firmware bug. Instead, if a
request completion indicates a reboot, we must poll and clear the
status word.
This bug was previously masked by use of an incorrect address for the
status word. Fix that, using the definition now included in
mcdi_pcol.h.

Some commands and constants have been renamed; adjust the code
accordingly.

Fix the following warnings:
WARNING: struct dev_pm_ops should normally be const
WARNING: static const char * array should probably be static const char * const
Similarly const-qualify struct i2c_board_info, struct i2c_algo_bit_data,
struct efx_ethtool_stat, struct efx_mtd_ops and struct siena_nvram_type_info.

Moves the Solarflare drivers into drivers/net/ethernet/sfc/ and
make the necessary Kconfig and Makefile changes.
