Subject: [PATCH AUTOSEL 4.19 131/671] clk: sunxi-ng: sun8i-a23: Enable PLL-MIPI LDOs when ungating it

From: Chen-Yu Tsai <wens@...e.org>

[ Upstream commit 108a459ef4cd17a28711d81092044e597b5c7618 ]

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.
