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
