clk: sunxi-ng: sun6i-a31: Enable PLL-MIPI LDOs when ungating it
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") Signed-off-by: Chen-Yu Tsai <wens@csie.org> Signed-off-by: Maxime Ripard <maxime.ripard@free-electrons.com>
