Subject: [PATCH 035/117] riscv: defconfig: Enable the Allwinner D1 platform
 and drivers

Now that several D1-based boards are supported, enable the platform in
our defconfig. Build in the drivers which are necessary to boot, such as
the pinctrl, MMC, RTC (which provides critical clocks), SPI (for flash),
and watchdog (which may be left enabled by the bootloader). Other common
onboard peripherals are enabled as modules.

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

The SoC devicetree uses bindings from the following series which have
not yet been merged:
- SRAM controller:
  https://lore.kernel.org/lkml/20220815041248.53268-1-samuel@sholland.org/
- NVMEM cell bits property change:
  https://lore.kernel.org/lkml/20220814173656.11856-1-samuel@sholland.org/
- In-package LDO regulators:
  https://lore.kernel.org/lkml/20220815043436.20170-1-samuel@sholland.org/

All three of these are required to set the correct I/O domain voltages
in the pin controller, which I would consider important to have in the
initial version of the devicetree.

The SoC devicetree does contain one small hack to avoid a dependency on
the audio codec binding, since that is not ready yet: the codec node
uses a bare "simple-mfd", "syscon" compatible.
