ALSA: hda/cs35l56: Call cs_dsp_power_down() before reloading firmware

Browse source 
When firmware is reloaded after a system resume cs_dsp_power_down() should
be called before calling cs_dsp_power_up().

The fw_patched flag should also be cleared and only set again if the
firmware download succeeded.
