[PATCH 1/9] ALSA: hda/cs35l56: Complete firmware reboot before calling cs_dsp_run()

Move the call to cs_dsp_run() in cs35l56_hda_fw_load() so that it
is after the CS35L56 has been reset/reinit'd and the regmap
cache has been synced.

cs_dsp_run() syncs up ALSA control cache values with the DSP memory
so this must not be done until the firmware has reinitialized.
