watchdog: lenovo_se10_wdt: Add support for SE10 Gen 2 platform

Browse Source 
The Lenovo SE10 Gen 2 platform uses a watchdog chip from the same family.
Watchdog functionality is the same, so update the driver with the new chip
ID.

Add the Gen 2 MTM's to enable support on the platform.

Tested on SE10 G2.
