ramips: 5.10: port and refresh patches, ralink drv Enable testing kernel. Fix compile errors by using new kernel APIs. Fix fuzz by manually editing patches to ensure the code goes in the right place. For 721-NET-no-auto-carrier-off-support.patch, revert upstream commit a307593a6 to keep the OpenWrt ralink driver operational. Add mt7621-pci-phy patch to select REGMAP_MMIO as discussed in PR #3693 and #3952. Run automatic quilt refresh on the rest.
