Subject: [PATCH 5/5] ASoC: cs35l56: Call wm_adsp_power_down() before reloading firmware

From: Simon Trimmer <simont@...nsource.cirrus.com>

When cs35l56_system_resume() needs to reload firmware it should call
wm_adsp_power_down() to put cs_dsp into a powered-down state before
cs35l56_secure_patch() or cs35l56_patch() calls wm_adsp_power_up().
