Logically, EFX_BUG_ON_PARANOID can never be correct. For, BUG_ON should
only be used if it is not possible to continue without potential harm;
and since the non-DEBUG driver will continue regardless (as the BUG_ON is
compiled out), clearly the BUG_ON cannot be needed in the DEBUG driver.
So, replace every EFX_BUG_ON_PARANOID with either an EFX_WARN_ON_PARANOID
or the newly defined EFX_WARN_ON_ONCE_PARANOID.

Simplify the code. Avoid race conditions caused by attributes
being created after hwmon device registration. Implicitly
(through hwmon API) add mandatory 'name' sysfs attribute.

Update the dates for files that have been added to in 2012-2013.
Drop the 'Solarstorm' brand name that's still lingering here.

Add support for power and current sensors, which need to be named
differently in sysfs. Power sensors also require values to be scaled
between MCDI and sysfs, and have no minimum value.
Add definitions of the power, current, fan, and additional temperature
and voltage sensors found on SFA6902F, SFN7022F and SFN7122F.
(Includes a bug fix from Andrew Jackson.)

Most call sites for efx_nic_alloc_buffer() are part of the probe or
reconfiguration paths and can allocate with GFP_KERNEL. A few others
should use GFP_NOIO (I think). Only one is in atomic context and
must use the current GFP_ATOMIC.

MCDI_DECLARE_BUF declares a variable as an MCDI buffer of the
requested length, adding any necessary padding.

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.
