[PATCH] ASoC: SOF: loader: load_firmware callback is mandatory, treat it like that

[Peter Ujfalusi]

Since the load_firmware callback in snd_sof_dsp_ops is mandatory and it
is tested during probe.

Move the snd_sof_load_firmware() wrapper to ops.h as inline and drop the
check of sof_ops(sdev)->load_firmware
