[PATCH v3 2/3] drm/bridge: sii902x: Enable I/O and core VCC supplies if present

On the SII9022, the IOVCC and CVCC12 supplies must reach the correct voltage before the reset sequence is initiated. On most boards, this assumption is true at boot-up, so initialization succeeds. However, when we try to initialize the chip with incorrect supply voltages, it will not respond to
