[PATCH 00/22] sunxi: Prepare platform Kconfig to support multiple architectures

[Samuel Holland]

sunxi is getting a new RISC-V platform, D1. We want to share as much of
the existing configuration as possible, to provide a familiar
environment, DRAM layout, partition layout, etc.

Because U-Boot includes all architecture Kconfig files at once, we must
use a symbol outside of both CONFIG_ARM and CONFIG_RISCV to contain
shared Kconfig options. I chose BOARD_SUNXI, corresponding to the file
location and somewhat following the BOARD_SPECIFIC_OPTIONS pattern.

I did a buildman run on this series. The only net option changes are the
expected ones:
 - Host-side USB gets enabled on several boards by the first patch
   (emlid_neutis_n5_devboard orangepi_zero2 pinephone pinetab tanix_tx6
   x96_mate teres_i)
 - CONFIG_BOARD_SUNXI gets added everywhere
 - CONFIG_SYS_I2C_MVTWSI gets enabled by the corresponding patch

Andre, please feel free to take any subset of these; they don't all have
to go in at once. And I'm open to suggestions about what instances of
ARCH_SUNXI should (not) be converted. Some of them are open to opinion.

I left alone the options in arch/arm/mach-sunxi/Kconfig that are covered
by other series (MMC CD/USB PHY/power pins, AXP GPIO).

After this series, the Kconfig changes needed for D1 support are quite
small, something like this commit:
https://github.com/smaeul/u-boot/commit/c12cf6c5d72f5327eff793518229ddbd41dcf729.patch

Adding SUNXI_MINIMUM_DRAM_MB certainly made things nicer. There are a
few options that probably still need some adjustment to respect it.
