gpio: pisosr: Use devm_mutex_init() 

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
   8431	   1808	    192	  10431	   28bf	drivers/gpio/gpio-pisosr.o

After:
=====
   text	   data	    bss	    dec	    hex	filename
   8112	   1736	    192	  10040	   2738	drivers/gpio/gpio-pisosr.o
