Subject: [PATCH] phy: allwinner: phy-sun6i-mipi-dphy: Constify structs

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
