phy-for-5.11

 - New phy drivers:
   - Mediatek MT7621 PCIe PHY (promoted from staging)
   - Ingenic USB phy driver supporting JZ4775 and X2000
   - Intel Keem Bay USB PHY driver
   - Marvell USB HSIC PHY driver supporting MMP3 SoC
   - AXG MIPI D-PHY driver

 - Updates:
   - Conversion to YAML binding for:
	- Broadcom SATA PHY
	- Cadence Sierra PHY bindings
	- STM32 USBC Phy
   - Support for Exynos5433 PCIe PHY
   - Support for Qualcomm SM8250 PCIe QMP PHY
   - Support for Exynos5420 USB2 phy
   - devm_platform_ioremap_resource conversion for bunch of drivers
