usb: storage: make const arrays static, reduces object code size
Don't populate const arrays on the stack, instead make them
static. Makes the object code smaller by over 1070 bytes:
Before:
text data bss dec hex filename
3505 880 0 4385 1121 drivers/usb/storage/option_ms.o
After:
text data bss dec hex filename
2269 1040 0 3309 ced drivers/usb/storage/option_ms.o
