phy: allwinner: phy-sun6i-mipi-dphy: Add the A100 DPHY variant

A100 features an updated DPHY, which moves PLL control inside the DPHY
register space (previously the PLL was controlled from the CCU). It also
requires a modified analog power-on sequence. This "combo PHY" can also
be used as an LVDS PHY, but that is not yet supported by the driver.
