arm64: dts: renesas: r8a779g3: Reinstate basic PCIe clock description for Sparrow Hawk
The 9FGV0441 PCIe clock generator can operate in autonomous mode, which
is the default mode. U-Boot currently does not have a driver for this
PCIe clock generator, but Linux 6.17 DT does describe the clock generator
in Sparrow Hawk board DT and this DT is included in U-Boot since commit
eea470fd7f6a ("Subtree merge tag 'v6.17-dts' of dts repo [1] into dts/upstream").
Reinstate basic PCIe clock description which matches the behavior of
Linux DT before Linux 6.17.y release in in U-Boot DT extras to allow
PCIe to be used on Sparrow Hawk board in U-Boot until the 9FGV0441
driver gets implemented or ported from Linux.
