Subject: [PATCH 3/4] arm64: dts: rockchip: Add vcc-supply to SPI flash on rk3566-pinetab2

As described on page 37 of PineTab2 Schematic-20230417, the SPI Flash's
VCC connector is connected to VCCIO_FLASH and according to page 6 of
that same schematic, that belongs to the VCC_1V8 power source.

This fixes the following warning:

  spi-nor spi4.0: supply vcc not found, using dummy regulator

Fixes: e7f4e924f46d ("dt-bindings: mtd: jedec,spi-nor: add optional vcc-supply")
