ALSA: drivers: make array 'names' const, reduces object code size
Don't populate array 'names' on the stack but instead make them static.
Makes the object code smaller by 50 bytes:
Before:
text data bss dec hex filename
21237 9192 1120 31549 7b3d linux/sound/drivers/dummy.o
After:
text data bss dec hex filename
21095 9280 1120 31495 7b07 linux/sound/drivers/dummy.o
(gcc version 7.2.0 x86_64)
