pinctrl: uniphier: make arrays static, reduces object code size

Don't populate const arrays on the stack, instead make them
static.  Makes the object code smaller nearly 1000 bytes. Also
line break wide lines to avoid checkpatch warnings.

Before:
   text	   data	    bss	    dec	    hex	filename
  13112	   1996	      0	  15108	   3b04	pinctrl-uniphier-core.o

After:
   text	   data	    bss	    dec	    hex	filename
  11642	   2476	      0	  14118	   3726	pinctrl-uniphier-core.o
