pinctrl: nomadik: follow whitespace kernel coding conventions

Fix strict checkpatch warnings relative to whitespace. Message types
addressed:

   ERROR: space required before the open parenthesis '('
   WARNING: quoted string split across lines
   CHECK: Alignment should match open parenthesis
   CHECK: Please don't use multiple blank lines
   CHECK: line length of 103 exceeds 100 columns
   CHECK: spaces preferred around that '+' (ctx:VxV)

Before: 1 errors, 2 warnings, 38 checks.
After:  0 errors, 1 warnings, 16 checks.
