[PATCH] clk: sunxi-ng: sun6i-a31: Enable PLL-MIPI LDOs when ungating it

[Chen-Yu Tsai]

The PLL-MIPI clock is somewhat special as it has its own LDOs which
need to be turned on for this PLL to actually work and output a clock
signal.

Add the 2 LDO enable bits to the gate bits. This fixes issues with
the TCON not sending vblank interrupts when the tcon and dot clock are
indirectly clocked from the PLL-MIPI clock.

Fixes: c6e6c96d8fa6 ("clk: sunxi-ng: Add A31/A31s clocks")

This can be queued for either 4.9 or 4.10.

The clock driver was introduced in 4.9,
but the users won't appear until 4.10.
