Derek Huang da3812208e chromeos/cr50_enable_update.c: Clear EC AP_IDLE flag
When AP boots up after Cr50 firmware update and reboot, AP finds
that Cr50 reset is required for Cr50 to pick the new firmware so
it trigger Cr50 reset and power off the system, AP expects system
will power on automatically after Cr50 reset. However this is not
the case for Chromebox, Chromebox EC set AP_IDLE flag when system
is shutting down, when AP_IDLE flag is set in EC, the system stays
at S5/G3 and wait for power button presssend. It cause an issue in
factory that the operator needs to press power button to power on
the DUT after Cr50 firmware update.

This patch sends EC command to direct EC to clear AP_IDLE flag
after AP shutdown so AP can boot up when Cr50 reset.

BUG=b:261119366
BRANCH=firmware-brya-14505.B
TEST=DUT boots up after Cr50 firmware update in factory test flow

The files in the coreboot src/vendorcode subdirectory are supplied by various hardware and software vendors to support their platforms. While these directories and files are a part of the coreboot project, their licenses, coding styles, and maintenance may be significantly different than the rest of the coreboot codebase.

By contributing these directories and files to the coreboot codebase, the authors and copyright holders have agreed to the use and modification of these files by the coreboot community, however the final ownership and responsibility still remains with the company that contributed the files.

The ideal goal would be to properly integrate these files into coreboot proper. But such undertakings should be coordinated with the owners. Community modification should in general be limited to fixing issues and adding functionality.

Licenses for the files were determined by the copyright holder when the files were contributed. All files here must have an open source license compatible with coreboot's GPL v2.
