arm: dts: add Nuvoton NPCM750 device tree

The NPCM7xx are a family of BMC's that include several chips as:
NPCM750, NPCM730 etc.

All of the NPCM7xx BMC's have the common modules like Cortex-A9, WDT, timers, etc, and there are a optional modules that can be added.

NPCM750 device tree already pushed to arm-soc.git:
https://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc.git/commit/?h=for-next&id=d6bdd009c21db3f677dd1d1bbb8c20bc819074bc

After discussion with Rob Herring we have modified the structure of the NPCM7xx device tree as follow:

nuvoton-common-npcm7xx device tree include all common modules nuvoton-npcm750 device tree include specific npcm750 modules, the nuvoton-npcm750 device tree include nuvoton-common-npcm7xx device tree

In addition, the NPCM7xx device tree include the following changes:
- watchdog module added
- clock module modification
- serial module modification

I will like to replace the device tree that pushed to arm-soc.git with this patch set.

Please review it, sorry if it cause more work after pushing NPCM750 device tree.

Thanks a lot,

Tomer
