Commit Message

From: Robert Chiras <[e-mail]>

Add compatible strings for i.MX8QM/i.MX8QXP platform. Remove
fsl,mipi-phy-gpr from required properties and add new reg space, since
i.MX8QM and i.MX8QXP use dedicate control and status register(csr) space.

Keep the same restriction for other compatible strings.

change from v2 to v3
- use dedicate csr register space
change from v1 to v2
- remove internal review tags
- remove reg maxitems:1
- remove 8ulp part
- add 8qxp compatible string and make 8qm failback to 8qxp
- limit reset and power domain number to 1 for 8qxp and 8qm
- remove power-domains change because 8qm/8qxp only need 1 power domain
