arm64: dts: rockchip: Add vcc-supply to SPI flash on rk3566-quartz64-b
The Quartz64 Model B has a Winbound 25Q64DWZPIG SPI flash chip,
identified as 'U13' on the component placement schematic.
In the Quartz 64 Model-B Schematic from 20220124 on page 17, we can see
that the VCC connector is connected to VCCIO_FLASH and page 4 shows that
that in turn is connected to the VCCIO2 domain.
That domain uses vcc_1v8 as its power source.
This fixes the following warning:
spi-nor spi4.0: supply vcc not found, using dummy regulator
