[PATCH v2] arm64: dts: renesas: r8a779g3: Describe generic SPI NOR support on Retronix R-Car V4H Sparrow Hawk board

[Marek Vasut]

Retronix R-Car V4H Sparrow Hawk EVTA1 is populated with Spansion S25FS512S,
EVTB1 is populated with Winbond W77Q51NW. Describe the SPI NOR using generic
"jedec,spi-nor" compatible, because both flashes can be auto-detected based on
their built-in IDs.
