arm64: dts: nuvoton: combine NPCM845 reset and clk nodes

Combine the NPCM845 reset and clock controller nodes into a single node
with compatible "nuvoton,npcm845-reset" in nuvoton-common-npcm8xx.dtsi,
using the auxiliary device framework to provide clock functionality.

Update the register range to 0xC4 to cover the shared reset and clock
registers at 0xf0801000.

Remove the separate nuvoton,npcm845-clk node, as the reset driver now
handles clocks via an auxiliary device.
