Subject: [PATCH v1 0/2] watchdog: npcm: Add reset status detection support

This series adds reset status detection support to the NPCM watchdog
driver for both NPCM7XX (Poleg) and NPCM8XX (Arbel) platforms.

Patch 1 updates the device-tree bindings to support reset status
detection on NPCM750 and NPCM8XX platforms. It introduces the
`nuvoton,card-reset-type`, `nuvoton,ext1-reset-type`, and
`nuvoton,ext2-reset-type` properties, and integrates the syscon
interface required for accessing the reset status registers.

Patch 2 implements the watchdog driver changes, including the reset
status detection infrastructure and platform restart support for both
NPCM7XX and NPCM8XX.
