Merge branch 'nuvoton/ma35d1' into soc/newsoc 

This patchset adds initial support for the Nuvoton ma35d1 SoC, including
initial device tree, clock driver, reset driver, and serial driver.

This patchset cover letter is based from the initial support for Nuvoton
ma35d1 to keep tracking the version history.

This patchset had been applied to Linux kernel 6.4.0-rc5
and tested on the Nuvoton ma35d1 SOM evaluation board.

(ma35d1 information: https://www.nuvoton.com/products/microprocessors/arm-cortex-a35-mpus/)
MA35D1 porting on linux-5.10.y can be found at: https://github.com/OpenNuvoton/MPU-Family

Link: https://lore.kernel.org/linux-arm-kernel/20230605040749.67964-1-ychuang570808@gmail.com/



[arnd: merging everything aside from the serial port driver for now, as
 that is still waiting for an Ack]

* nuvoton/ma35d1:
  reset: Add Nuvoton ma35d1 reset driver support
  clk: nuvoton: Add clock driver for ma35d1 clock controller
  arm64: dts: nuvoton: Add initial ma35d1 device tree
  dt-bindings: serial: Document ma35d1 uart controller
  dt-bindings: arm: Add initial bindings for Nuvoton platform
  dt-bindings: reset: nuvoton: Document ma35d1 reset control
  dt-bindings: clock: nuvoton: add binding for ma35d1 clock controller
  arm64: defconfig: Add support for Nuvoton MA35 family SoCs
  arm64: Kconfig.platforms: Add config for Nuvoton MA35 platform
