arm64: dts: mipi-lvds: fix mipi rx/tx clocks
By default, the MIPI RX and TX clocks are parented to the BYPASS clock,
but it seems that this doesn't work on QXP. Since these clocks can also
be parented to MIPI_PLL and MIPI_PLL_DIV2, use the MIPI_PLL_DIV2 with a
fixed rate of 432M and parent the RX and TX clocks to it.
This works on both QM and QXP.
