[v5,00/11] riscv: Allwinner D1/D1s platform support

This series adds the Kconfig/defconfig plumbing and devicetrees for a
range of Allwinner D1 and D1s-based boards. Many features are already
enabled, including USB, Ethernet, and WiFi.

This version drops all boards/nodes with missing YAML bindings, so at
least some support can get merged for v6.3.

Note that validation requires dt-schema v2022.12 or newer.

I thoroughly tested earlier versions of this series (DMIC, Ethernet,
LEDs, MMC, PMIC, touch, and USB, where available) on several boards.
v4/v5 have trivial changes, and I boot-tested them on sun20i-d1-nezha.

Changes in v5:
 - Drop system LDOs because the binding is still not merged
 - Drop the configuration for LDOA and LDOB
 - Drop the ClockworkPi and DevTerm DTS, since it needs the system LDOs

Changes in v4:
 - Rebase on v6.2-rc1 + soc2arch-immutable
 - Drop the now-redundant 'select SIFIVE_PLIC'

Changes in v3:
 - Drop dummy DCXO clock-frequency property
 - Decrease the PLIC's riscv,ndev property to 175
 - Fix `make W=1 dtbs` warnings (unnecessary #address/#size-cells)
 - Drop mmc aliases
 - Change LED_FUNCTION_BACKLIGHT to LED_FUNCTION_STATUS (the backlight
   regulator is disconnected by default, so this is a standalone LED)
 - Fix `make W=1 dtbs` warnings (missing reg properties)
 - ARCH_SUNXI depends on MMU && !XIP_KERNEL

Changes in v2:
 - Add MangoPi MQ (non-Pro) board
 - Split into separate files for sharing with D1s/R528/T113
 - Use SOC_PERIPHERAL_IRQ macro for interrupts
 - Rename osc24M to dcxo and move the frequency to the board DTs
 - Drop analog LDOs due to the missing binding
 - Correct tcon_top DSI clock reference
 - Add DMIC, DSI controller, and DPHY (bindings are in linux-next)
 - Add CPU OPP table
 - Common regulators moved to MangoPi MQ patch, removed analog LDOs
 - Removed LRADC (depends on analog LDOs)
 - Added XR829 host-wake interrupt
 - Added DMIC sound card to Lichee RV dock and Lichee RV 86 Panel
 - Removed LRADC (depends on analog LDOs)
 - Added LED (GPIO shared between onboard LED and backlight regulator)
 - Sort Kconfig as if we had done s/SOC_/ARCH_/ for future-proofing
