gpio: make several const arrays static, shrinks object size
Don't populate the const read-only arrays 'port' on the stack but
instead make them static. Makes the object code smaller:
Before:
text data bss dec hex filename
8542 4088 672 13302 33f6 drivers/gpio/gpio-gpio-mm.o
10959 4952 832 16743 4167 drivers/gpio/gpio-104-dio-48e.o
9022 5064 1408 15494 3c86 drivers/gpio/gpio-104-idi-48.o
After:
text data bss dec hex filename
8372 4144 672 13188 3384 drivers/gpio/gpio-gpio-mm.o
10790 5008 832 16630 40f6 drivers/gpio/gpio-104-dio-48e.o
