clk: renesas: r9a09g056: Remove entries for WDT{0,2,3}

The Renesas RZ/V2N SoC (a.k.a. r9a09g056) comes with 4 watchdogs.

As it turns out, it only makes sense for Linux to have access to
WDT1.

Remove the clock and reset entries for WDT{0,2,3} to prevent
interfering with the CM33 core.

This change is harmless as only WDT1 is currently used in Linux,
there are no users for the WDT{0,2,3} IPs.
