ASoC: rt715-sdca-sdw: use first_hw_init flag on resume
The intent of the status check on resume was to verify if a SoundWire
peripheral reported ATTACHED before waiting for the initialization to
complete. This is required to avoid timeouts that will happen with
'ghost' devices that are exposed in the platform firmware but are not
populated in hardware.
Unfortunately we used 'hw_init' instead of 'first_hw_init'. Due to
another error, the resume operation never timed out, but the volume
settings were not properly restored.
This patch renames the status flag to 'first_hw_init' for consistency
with other drivers (was 'first_init')
