The register offset for the mipi-csi clk is off by 4, a copy paste
error from the mipi-dsi clk.

The PLLs have a "lock" bit in their configuration registers which
indicate if the PLL has locked on to the requested clock rate. We
check this bit in the .set_rate op. The PLL cannot lock on if it's
not running, which might be a false positive (warning).
Set the CLK_SET_RATE_UNGATE flag for all PLLs so whenever clk_set_rate
is called on them, they get enabled and the "lock" check is really
checking the PLL.

The LCD controller and HDMI controller use the LCDx-CHy and HDMI clocks
to generate their dot clocks. To be able to generate a full range of
possible clock rates, the parent PLL clock rates should also be changed.

Add a new style driver for the clock control unit in Allwinner A31/A31s.
A few clocks are still missing:
- MIPI PLL's HDMI mode support
- EMAC clock
