Sunxi arm64 doesn't have separate configs for
h5 and a64 so enable SUNXI_RSB bus for ARM64.

The proper vendor name is "Allwinner".

Applied with the following commit message:

arm64: defconfig: Enable MFD_AXP20X_RSB

The Allwinner A64 SoC is paired with the X-Powers AXP803 PMIC over the
Reduced Serial Bus (RSB).

Enable the driver for this PMIC.

Applied with the following commit message:

arm64: defconfig: Enable REGULATOR_AXP20X

The Allwinner A64 SoC is paired with the X-Powers AXP803 PMIC over the
Reduced Serial Bus (RSB). The regulators of this PMIC supply all power
rails of the SoC and many external peripherals.

Enable the driver for the regulators of this PMIC.

The commit message is missing a lot of details. It assumes the
reader knows about the A64 SoC and that it uses the RSB bus to
communicate with the PMIC.

Applied for 4.14 with the following commit message:

bus: sunxi-rsb: Enable by default for ARM64

Allwinner's A64 SoC uses the "Reduced Serial Bus" to communicate with
its companion PMIC.

Since arm64 does not have separate defconfigs for each platform or
processor family, enable this driver by default for ARM64 as well.
Note that the Kconfig symbol already depends on ARCH_SUNXI.
