ASoC: Writing register default value for the reset register
The WM8983 can be reset by performing a write of any value to the software reset register. To avoid writing to the software reset register while resume, we should write the same value in wm8983_reg_defs to software reset register in wm8983_probe(). The write to the reset register is suppressed by the cache restore code when it skips writes of default registers.
