Subject: [PATCH 3/5] regulator: ltc3676: Constify ltc3676_regulators

ltc3676_regulators is not modified and can be made const to allow the
compiler to put it in read-only memory.

Before:
   text    data     bss     dec     hex filename
   4361    2064       8    6433    1921 drivers/regulator/ltc3676.o

After:
   text    data     bss     dec     hex filename
   6121     304       8    6433    1921 drivers/regulator/ltc3676.o
