  soc: imx6qp: Use GENPD_FLAG_ALWAYS_ON for PU errata (2018-07-17 14:12:14 +0800)

----------------------------------------------------------------
i.MX drivers update for 4.19:
 - 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.
