When enabled, the EC will mirror the firmware contained inside the
coreboot ROM. This allows it to be updated at the same time as
coreboot.

The Lite Mk IV's can enable fast charging, with support up to 100W
via USB-C PD 3.0.
The default for this is disabled, as it can reduce battery life
span. This patch adds the option to enable fast charging, by
writing 0x01 to 0x18 in the EC space.
