[PATCH] clk: renesas: r9a07g043: Hide WDT2 clock and reset entries for RZ/Five

[Prabhakar]

From: Lad Prabhakar <prabhakar.mahadev-lad.rj@xxxxxxxxxxxxxx>

Make the clock and reset entries for WDT2 only visible for RZ/G2UL (ARM64)
as the RZ/Five SoC doesn't have the WDT2 channel.

While at it, add the WDT2 clocks to r9a07g043_crit_mod_clks[] list as WDT
CH2 is specifically to check the operation of Cortex-M33 CPU on the RZ/G2UL
SoC and we dont want to turn off the clocks of WDT2 if it isn't enabled by
Cortex-A55.

Fixes: 95d48d270305 ("clk: renesas: r9a07g043: Add support for RZ/Five SoC")
