[PATCH 0/2] arm64: dts: rockchip: NanoPi R2S Plus: fix io-domains, enable SDIO Wi-Fi

[Deomid rojer Ryabkov]

Patch 1 fixes the VCCIO4/VCCIO6 supplies of the NanoPi R2S Plus, which
were inherited from the NanoPi R2S but are wired differently (see the
schematics referenced in the patch).

Patch 2 enables the M.2 E-key SDIO slot, which FriendlyElec populates
with an optional RTL8822CS (Fn-Link 6222B-SRC) Wi-Fi module.

With these the module works at 50 MHz high-speed. Reaching SDR104 needs
an mmc core fix for the module's CMD11 handling, posted to linux-mmc:

Tested on a NanoPi R2S Plus; dtbs_check reports no new warnings.
