iio: adc: PAC1934: Use devm_mutex_init()

Browse Source 
Use devm_mutex_init() instead of hand-writing it.

This saves some LoC, improves readability and saves some space in the
generated .o file.

Before:
======
   text	   data	    bss	    dec	    hex	filename
  50985	  23992	    192	  75169	  125a1	drivers/iio/adc/pac1934.o

After:
=====
   text	   data	    bss	    dec	    hex	filename
  50654	  23920	    192	  74766	  1240e	drivers/iio/adc/pac1934.o
