The MEC LPC protocol is supported in Linux' cros_ec_lpcs driver, but not
in ectool's "local" implementation. However, cros_ec_lpcs will not load
on the Framework Laptop due to an I/O port conflict^1. Therefore,
ectool's local implementation is required to support the MEC protocol on
kernel versions that do not contain a fix for the I/O conflict.
I've not taken care to deduplicate the protocol code with comm-lpc,
as there is little value in sharing due to the different order in which
command data are checksummed.
