[ Upstream commit 14653942de7f63e21ece32e3901f09a248598a43 ]

The R-Car V3U clock driver defines the R and OSC clocks using R-Car Gen3
clock types.  However, The R-Car V3U clock driver does not use the R-Car
Gen3 clock driver core, hence registering the R and OSC clocks fails:

    renesas-cpg-mssr e6150000.clock-controller: Failed to register core clock osc: -22
    renesas-cpg-mssr e6150000.clock-controller: Failed to register core clock r: -22

Fix this by introducing clock definition macros specific to R-Car V3U.
Note that rcar_r8a779a0_cpg_clk_register() already handled the related
clock types.  Drop the now unneeded include of rcar-gen3-cpg.h.
