sun6i_dphy_ops and sun6i_dphy_regmap_config are not modified so make them
const structs to allow the compiler to put them in read-only memory.
Before:
text data bss dec hex filename
4407 1944 64 6415 190f drivers/phy/allwinner/phy-sun6i-mipi-dphy.o
After:
text data bss dec hex filename
4835 1496 64 6395 18fb drivers/phy/allwinner/phy-sun6i-mipi-dphy.o
