Subject: [PATCH v3 0/2] platform/x86: portwell-ec: Add watchdog suspend/resume
 and hwmon

This patch series adds suspend/resume support for the watchdog (patch 1/2)
and hwmon monitoring functionality (patch 2/2) to the Portwell EC driver.
These changes enable better power management and sensor reporting.

Tested on Portwell NANO-6064.
