arm64: dts: renesas: r8a779g3: Describe generic SPI NOR support on Retronix R-Car...

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.
