- Handle i.MX6SL chip errata ERR006287 in the safest possible way by
keeping the DISP domain always-on, because Upon resuming from power
gating, the modules in the display power domain (eLCDIF, EPDC, PXP
and SPDC) might fail to perform register reads correctly.
- Use GENPD_FLAG_ALWAYS_ON flag for i.MX6QP PU ERR009619 handling.
It is functionally identical to the exsiting implementation but
simpler and slightly faster.
