[Richard Zhu <hongxing.zhu@nxp.com>]

V5 main changes:
Thanks for Niklas' kind help.
- Drop 32bit DMA limit commit, since the "dma-ranges" of DT can overcome
  this limitation.

V4 main changes:
Thanks for Niklas' comments.
- Update the commit message in #2 patch of v4.
- Split the clean up unrelated codes to #3 and #4 of v4.
- Remove the Cc: stable@vger.kernel.org and Fixes tag in #5 of v4.

V3 main changes:
- Use GENMASK() macro to define the _MASK.
- Refine the macro names.

V2 main changes:
- Add Rob's reviewed-by in the binding patch.
- Re-name the error out lables and new RXWM macro more descriptive.
- In #3 patch, add one fix tag, and CC stable kernel.

Based on i.MX8QM HSIO PHY driver, refine i.MX8QM SATA driver by using PHY
interface.
