gpio: 104-dio-48e: make array 'ports' static, shrinks object size
Don't populate the const read-only array 'ports' on the stack but instead
make it static. Makes the object code smaller by over 100 buytes:
Before:
text data bss dec hex filename
10959 4952 832 16743 4167 drivers/gpio/gpio-104-dio-48e.o
After:
text data bss dec hex filename
10790 5008 832 16630 40f6 drivers/gpio/gpio-104-dio-48e.o
(gcc version 7.2.0 x86_64)
