mtd: mtdswap: make array 'name' static const, shrinks object size
Don't populate the read-only array 'name' on the stack but instead
make it static and constify it. Makes the object code smaller by 35
bytes:
Before:
text data bss dec hex filename
26304 4444 352 31100 797c drivers/mtd/mtdswap.o
After:
text data bss dec hex filename
26205 4508 352 31065 7959 drivers/mtd/mtdswap.o
(gcc version 7.2.0 x86_64)
