MLK-18649-3 arm64: dts: fsl-imx8qxp-mek: Supply aux PD for LVDS dual chan mode
When ldb works in dual LVDS channel mode, it consumes two MIPI/LVDS combo
subsystems, one primary and the other auxiliary. Each subsystem is powered
by it's own power domain. So, the dual channel mode needs two power domains.
The pd_mipi_dsi_0/1_dual_lvds power domains may supply two power domains to
the ldb1/2 nodes respectively. Thus, let's hook them to the ldb1/2 nodes
when ldb1/2 works in dual channel mode.
