pinctrl: actions: pinctrl-s500: Constify s500_padinfo[]

s500_padinfo[] is never modified and should be made 'const' to allow
the compiler to optimize code generation, i.e. put it in the text
section instead of the data section.

Before:
   text    data     bss     dec     hex filename
  12503    5088       0   17591    44b7 drivers/pinctrl/actions/pinctrl-s500.o

After:
   text    data     bss     dec     hex filename
  14435    3156       0   17591    44b7 drivers/pinctrl/actions/pinctrl-s500.o
