clk: renesas: Add R8A779G0 V4H clock tables

Add clock tables for R8A779G0 V4H SoC from Linux next
commit 058f4df42121 ("Add linux-next specific files for 20230228")

There is an adjustment to the clock tables to make them easier suitable
for U-Boot, PLL2 is not treated as GEN4 PLL type PLL2_VAR, but rather a
plain PLL2. This should be sufficient until PLL2_VAR is implemented in
the clock core.

[Marek: Sync with Linux next 20230228 . Update from CLK to CPG core driver
        Treat PLL2 as non-PLL2_VAR for now]
