ENGR00270573-2 [MX6SL]Add support for dynamic Power Gating of the display MIX

The display MIX can be power gated when EPDC, PXP and LCDIF are all inactive.
This will save around 1.5mW-1.8mW of power in system IDLE mode.
Need to re-initialize the EPDC and PXP whenever the display MIX is
powered up as all the register state is lost when the display MIX is
power gated.
