ASoC: wm8753: fix initialization
Without that fix the wm8753 SPI initialization fails, and then produces
a kernel panic during boot with the following call trace:
Unable to handle kernel paging request at virtual address 37386d9b

The commit d3398ff05907167f463e119421b053ce043741d1
( ASoC: Convert WM8753 to direct regmap API usage ) introduced
the problem.
Thanks to Lars-Peter Clausen for helping me a bit during the debugging.
