Subject: [PATCH 1/5] regulator: anatop: Constify anatop_core_rops

anatop_core_rops is not modified and can therefore be made const which
allows the compiler to put it in read-only memory.

Before:
   text    data     bss     dec     hex filename
   4502     412       0    4914    1332 drivers/regulator/anatop-regulator.o

After:
   text    data     bss     dec     hex filename
   4634     280       0    4914    1332 drivers/regulator/anatop-regulator.o
