arm64: dts: allwinner: a64: explicitly assign clock parent for TCON0
TCON0 seems to need a different clock parent depending on output type.
For RGB it has to be PLL-VIDEO0-2X, while for DSI it has to be PLL-MIPI,
so select it explicitly.
Video output doesn't work if incorrect clock is assigned.
On my Pinebook I manually configured PLL-VIDEO0-2X and PLL-MIPI to the same
rate, and while video output works fine with PLL-VIDEO0-2X, it doesn't
work at all (as in no picture) with PLL-MIPI.
Fixes: ca1170b69968 ("clk: sunxi-ng: a64: force select PLL_MIPI in TCON0 mux")
