hdmitx: optimize hpll suspend

PD#165090: hdmitx: optimize hpll suspend

The BIT definition of RESET / ENABLE in G12A is different from
earlier chips.
HPLL suspend workflow:
1. set RESET as 1
2. delay 50us
3. set ENABLE as 0
Resume workflow is inverse, but no need anymore, it will be set
in set_disp_mode_auto().
