ec: Add support for EC used on Purism Librem laptops
This adds basic ACPI support for the EC used on Purism Librem laptops. The EC firmware appears to use the topstar laptop interface that has support in the linux kernel for handling the special keys. Supported functions: - Battery information - AC presence - Lid switch - Special keys (after loading topstar-laptop driver in linux) - EC events for turbo enable/disable when on AC power Things it does not do: - EC SMI handling - Fan is left under EC control This was developed and tested on a Librem 13 laptop, and has not been directly tested on an Librem 15.
