vendorcode/google/chromeos: Introduce helper for CSE board reset

When CSE Lite jumps from RO to RW, certain boards need to request
Embedded Controller (EC) to trigger cold reset of SoC. This change
introduces a helper to override the default global reset.

BUG=None
TEST=Ensure that Drawcia board boots to OS. Ensure that global reset is
triggered when cr50 is running firmware versions newer than 0.0.22. On
cr50 versions 0.0.22 or older, EC triggers cold reset of AP.
