Subject: [PATCH] clk: renesas: r9a07g043: Fix HP clock source for RZ/Five

According to the Rev.1.20 hardware manual for the RZ/Five SoC, the clock source for HP is derived from PLL6 divided by 2. Correct the implementation by configuring HP as a fixed clock source instead of a MUX.

The `CPG_PL6_ETH_SSEL' register, which is available on the RZ/G2UL SoC, is not present on the RZ/Five SoC, necessitating this change.
