Fix PHY init timeout issues:

1. Clock Stability issue causing PHY timeout

2. Timeout taking longer than needed on AC5X.
   Solve by constantly testing the PHY init bit
   until it toggles, but up to 100X timeout factor.

v2:
    1) convert polling loop to read_poll_timeout()
       for both patches.

v3:
    1) Add Acked-by, Fixes and CC for stable

Elad Nachman (2):
  mmc: xenon: fix PHY init clock stability
  mmc: xenon: add timeout for PHY init complete
