mb/google/fatcat: Enable EC ACPI memmap for Microchip EC

This commit enables ACPI memory mapping for fatcat boards featuring a
Microchip Embedded Controller (EC). This allows the operating system
to access and read various information from the EC.

The Microchip EC does not directly map these registers to I/O space,
necessitating the use of an indirection mechanism for register access.

TEST=/sys/class/power_supply/BAT0/* reports consistent values
