ASoC: cs35l56: Firmware file must match the version of preloaded firmware
Check during initialization whether the firmware is already patched.
If so, include the firmware version in the wm_adsp fwf_name string.
If the firmware has already been patched by the BIOS the driver
can only replace it if it has control of hard RESET.
If the driver cannot replace the firmware, it can still load a wmfw
(for ALSA control definitions) and/or a bin (for additional tunings).
But these must match the version of firmware that is running on the
CS35L56.
The firmware is pre-patched if FIRMWARE_MISSING == 0.
Including the firmware version in the fwf_name string will
qualify the firmware file name:
Normal (unpatched or replaceable firmware):
cs35l56-rev-dsp1-misc[-system_name].[wmfw|bin]
Preloaded firmware:
cs35l56-rev[-s]-VVVVVV-dsp1-misc[-system_name].[wmfw|bin]
Where:
[-s] is an optional -s added into the name for a secured CS35L56
VVVVVV is the 24-bit firmware version in hexadecimal.
