HID: hid-lg: make array cbuf static const to shink object code size
Don't populate array cbuf on the stack, instead make it static.
Makes the object code smaller by over 110 bytes:
Before:
text data bss dec hex filename
15096 3504 128 18728 4928 drivers/hid/hid-lg.o
After:
text data bss dec hex filename
14884 3600 128 18612 48b4 drivers/hid/hid-lg.o
