[PATCH v3 1/4] arm64: dts: imx8-ss-hsio: Add PCIe and SATA support

[PATCH v3 1/4] arm64: dts: imx8-ss-hsio: Add PCIe and SATA support

[Frank Li]

From: Richard Zhu <hongxing.zhu@nxp.com>

Add PCIe support for i.MX8QXP, i.MX8QM and i.MX8DXL.
Add SATA support for i.MX8QM, which is in hsio subsystem and is shared with
PCIe PHY.

Change from v2 to v3
- move fsl,max-link-speed after common property
- Add sata description at commit message.
- Fix hsio bus's range overlaps

Change from v1 to v2
- none

On going discussion:
https://lore.kernel.org/imx/20240930-pci_fixup_addr-v3-2-80ee70352fc7@nxp.com/
don't affect this dts.
This work for with/without above patches.
