[PATCH] arm64: dts: rockchip: Enable SD UHS-I modes on ROCK Pi 4

[Igor Velkov]

The RK808 sleep voltages do not take effect on ROCK Pi 4. Its SLEEP
pin is wired to GPIO1_A5 (AP_PWROFF), and nothing muxes that pin to
AP_PWROFF: the DT has no ap_pwroff pinctrl (NanoPi 4 has one), and
U-Boot passes no suspend GPIOs to TF-A. Read back on a ROCK Pi 4A:
GPIO1_A5 is a GPIO input, low. The vcc_sdio sleep state is also the
same as on rockpro64, roc-pc and other RK3399 boards with SDR104.

The io-domain race is what the PCI patch linked under the commit
message fixes:
