98fb2b95d2 clk: sunxi-ng: enable so-said LDOs for A33 SoC's pll-mipi clock
In the user manual of A33 SoC, the bit 22 and 23 of pll-mipi control
register is called "LDO{1,2}_EN", and according to the BSP source code
from Allwinner [1], the LDOs are enabled during the clock's enabling
process.

The clock failed to generate output if the two LDOs are not enabled.

Add the two bits to the clock's gate bits, so that the LDOs are enabled
when the PLL is enabled.

5519cf23ad clk: sunxi-ng: Fix reset offset for the A23 and A33
There's been a copy and paste mistake in the A23 and A33 from the H3,
leading in the reset offset for the UART and I2C.

d05c748bd7 clk: sunxi-ng: Add A33 CCU support
This commit introduces the clocks found in the Allwinner A33 CCU.

Since this SoC is very similar to the A23, and we share a significant share
of the DTSI, the clock IDs that are going to be used will also be shared
with the A23, hence the name of the various header files.
