Christian Hewitt 762c821b97 arm64: dts: meson: bananapi-m5: switch VDDIO_C pin to OPEN_DRAIN
[ Upstream commit 856968e066 ]

For proper warm (re)boot from SD card the BPI-M5 board requires TFLASH_VDD_EN
and VDDIO_C pins to be switched to high impedance mode. This can be achieved
using OPEN_DRAIN instead of ACTIVE_HIGH to leave the GPIO pins in input mode
and retain high state (pin has the pull-up).

This change is inspired by meson-sm1-odroid.dtsi where OPEN_DRAIN has been
used to resolve similar problems with the Odroid C4 board (TF_IO in the C4
dts is the equivalent regulator).
