arm64: dts: renesas: r8a779h0: Add remaining HSCIF nodes

Browse Source 
Add device nodes for the remaining High Speed Serial Communication
Interfaces with FIFO (HSCIF) on the Renesas R-Car V4M (R8A779H0) SoC,
including DMA support and the optional external clock source used by
HSCIF2.

Based on a patch in the BSP by Nghia Nguyen.
