platform/x86: portwell-ec: Add GPIO and WDT driver for Portwell EC
Adds a driver for the ITE Embedded Controller (EC) on Portwell boards.
It integrates with the Linux GPIO and watchdog subsystems to provide:
- Control/monitoring of up to 8 EC GPIO pins.
- Hardware watchdog timer with 1-255 second timeouts.
The driver communicates with the EC via I/O port 0xe300 and identifies
the hardware by the "PWG" firmware signature. This enables enhanced
system management for Portwell embedded/industrial platforms.
