Merge tag 'thead-dt-for-v6.12' of https://github.com/pdp7/linux into soc/dt

T-HEAD Devicetrees for v6.12

Add SPI controller node to th1520.dtsi and enable spi0 on the BeagleV
Ahead and LicheePi 4A.

The TH1520 AP_SYS clock driver landed in v6.11 so convert multiple
peripherals like mmc and uart from fixed clocks to the clock controller.

All of these patches have been successfully tested in the latest
linux-next releases.
