arm64: dts: rockchip: add HDMI pinctrl to rk3588-tiger SoM

The Tiger SoM routes all relevant HDMI pins to its Q7 connector.
Some from the M0 and some from the M1 set of pins.

Add the necessary pinctrl entry to the hdmi controller for the SoM.
Not all baseboards may use all pins, but even for them it'll serve
documentation purposes.
