pmdomain: rockchip: Fix PD_VCODEC for RK3588
>From the RK3588 TRM Table 7-1 RK3588 Voltage Domain and Power Domain Summary,
PD_RKVDEC0/1 and PD_VENC0/1 rely on VD_VCODEC which require extra voltages to
be applied, otherwise it breaks RK3588-evb1-v10 board after vdec support landed[1].
The panic looks like below:
rockchip-pm-domain fd8d8000.power-management:power-controller: failed to set domain 'rkvdec0' on, val=0
rockchip-pm-domain fd8d8000.power-management:power-controller: failed to set domain 'rkvdec1' on, val=0
...

Chaoyi pointed out the PD_VCODEC is the parent of PD_RKVDEC0/1 and PD_VENC0/1, so checking
the PD_VCODEC is enough.
