Subject: [PATCH] arm64: dts: rockchip: Add vcc-supply to SPI flash on Pinephone Pro
As documented in the PinephonePro-Schematic-V1.0-20211127.pdf,
page 11, the SPI Flash's VCC pin is connected to VCC_1V8 power
source. This fixes the following warning:
spi-nor spi1.0: supply vcc not found, using dummy regulator
