arm64: renesas: r8a779g3: Disable dual-rank DRAM on Retronix R-Car V4H ES2 Sparrow Hawk

The R-Car V4H SoC before rev.3.0 can not support dual-rank LPDDR5 DRAM.
This affects 16 GiB dual-rank DRAM configuration of Retronix R-Car V4H
Sparrow Hawk board. Fall back to 8 GiB single-rank DRAM configuration
on such systems instead.
