ec/google/chromeec: Enable ACPI memory mapping for Microchip EC

This commit introduces an automatic linkage between the Microchip
EC (EC_GOOGLE_CHROMEEC_MEC) and ACPI memory
mapping (EC_GOOGLE_CHROMEEC_ACPI_MEMMAP) options. This linkage is
enabled when the Microchip EC is selected.

Certain data registers in Microchip ECs cannot be accessed via I/O
space. Instead, an indirection mechanism is required for register
access. When using such an EC, coreboot must publish ACPI information
to access these data registers through ACPI data ports 66h/62h.

Analysis of the coreboot codebase has revealed that the
EC_GOOGLE_CHROMEEC_MEC and EC_GOOGLE_CHROMEEC_ACPI_MEMMAP options are
consistently used together. This commit streamlines this dependency by
linking the two options.

TEST=/sys/class/power_supply/BAT0/* reports consistent values on
     fatcat board.
