platform/chrome: cros_ec_lpc: switch primary DMI data for Framework Laptop

Browse Source 
Framework Computer appears to be moving away from the Microchip embedded
controller seen in the Framework Laptop 13 with Intel Core 11th, 12th
and 13th generation processors. All newer models use a Nuvoton NPCX
embedded controller.

Changing the default DMI match for Framework's products to match their
newer product lines will reduce churn in this part of the cros_ec_lpc
driver.

The new match tables are:

- Microchip EC models
  - "Laptop" (product, exact match) for the 11th gen. Intel Core
  - "12th Gen Intel Core" (product, exact match)
  - "13th Gen Intel Core" (product, exact match)
- Nuvoton NPCX models
  - "Laptop" (product family, partial match)
