Geert Uytterhoeven fd3c2f3826 clk: renesas: r8a7792: Add new CPG/MSSR driver
Add a new R-Car V2H Clock Pulse Generator / Module Standby and Software
Reset driver, using the CPG/MSSR driver core.  This will enable support
for module resets, which are not supported by the existing driver.

The old driver can still be used through a Kconfig option, to preserve
backward compatibility with old DTBs.

Enable backward compatibility with old device trees describing a
hierarchical representation of the various CPG and MSTP clocks.
Say Y if you want your kernel to work with old DTBs.
