platform/chrome: cros_ec_lpc: add quirks for the Framework Laptop (AMD)
The original Framework Laptop 13 platform (Intel 11th, 12th, and 13th
Generation at this time) uses a Microchip embedded controller in a
standard configuration.
The newer devices in this product line--Framework Laptop 13 and 16 (AMD
Ryzen)--use a NPCX embedded controller. However, they deviate from the
configuration of ChromeOS platforms built with the NPCX EC.
* The MMIO region for EC memory begins at port 0xE00 rather than the
expected 0x900.
cros_ec_lpc's quirks system is used to address this issue.
