scsi: ufs: mediatek: Fix vsx/vccqx control logic
VSX (the upper layer of VCCQ/VCCQ2) should:
1. Always set to hpm mode if ufs device is active.
2. Enter lpm mode only if ufs device is not active.
VCCQX should:
1. Keep hpm mode if vccq and vccq2 not set in dts.
2. Keep hpm mode if vcc not set in dts keep vcc always on.
3. Keep hpm if broken vcc keep vcc always on and not allow vccq lpm.
4. Except upper case, can enter lpm mode if ufs device is not active.
