Subject: [PATCH v4 0/4] renesas: r8a779g0: Enable VSPX on R-Car V4H

The series enables the two VSPX instances connected to the R-Car ISP
on Renesas R-Car V4H. Define clock identifiers based on the MSTPCR id
for the VSPX instances and defined device nodes in the V4H .dts file.

The VSPX modules interface with extenal memory through dedicated FCP
instances named FCPVX. Before defining VSPDX, define and enable the
FXPVX instances as well.

Testd on V4H White-Hawk by reading the FCPVX and VSPX version registers
during system boot.
