Allwinner SoC device tree changes for 6.11

This includes a commit shared with the clk tree. This commit adds clock
and reset indices to the device tree binding, and thus is needed for
both the device tree and driver changes.

ARM64 device tree and binding-only changes
- Add LRADC (low resolution ADC for resistor network based keys) for H616 SoC
- Add cache information for A64, H6, and H616 SoCs
- Correct model names and descriptions for Pine64 boards
- Add GPADC (general purpose ADC) for H616 SoC
- Add ADC joysticks based on GPADC for anbernic-rg35xx-h board
- Add additional CPU OPPs for the H700 on top of existing H616 ones
- Enable DVFS for rg35xx boards
- Add IOMMU for H616 SoC

RISC-V device tree changes
- Add system LDOs to D1s/T113 SoC
- Add ClockworkPi and DevTerm device trees
