[PATCH v3 4/6] clk: nuvoton: ma35d1: Add missing WDT/WWDT parent clocks

[Miquel Raynal]

The WDT and WWDT muxes list PCLK3/4096 and PCLK4/4096 among their
possible parents, but the driver never registers the corresponding
clocks, so these parents could never be used.

Add pclk3_div4096 and pclk4_div4096 as fixed factor children of pclk3
and pclk4 and expose them through the clock provider.
