[PATCH v1 4/4] cros_ec_lpc: add quirks for the Framework Laptop

["Dustin L. Howett" <dustin@howett.net>]

The original Framework Laptop contains a Microchip EC, but the newer
ones have switched to an NPCX EC which uses the standard linear MMIO
protocol for host commands and EC memory.

However, those newer Framework Laptops diverge from the standard
ChromeOS EC in two important ways:

1. The ACPI table for PNP0C09 only claims I/O ports 0x800 to 0x8FE
   instead of the traditional 0x8FF
2. The MMIO region for EC memory begins at port 0xE00 rather than the
   traditional 0x900.

cros_ec_lpc's quirks system addresses both of these issues.
