clk: renesas: r8a779a0: Fix R and OSC clocks
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.
Fixes: 17bcc8035d2d19fc ("clk: renesas: cpg-mssr: Add support for R-Car V3U")
