Subject: [PATCH 4/5] regulator: max8907: Constify static structs

These are not modified so make them const to allow the compiler to put
them in read-only memory.

Before:
   text    data     bss     dec     hex filename
   2753    7328       0   10081    2761 drivers/regulator/max8907-regulator.o

After:
   text    data     bss     dec     hex filename
   9405     684       0   10089    2769 drivers/regulator/max8907-regulator.o
