Hello build bot (Jenkins), Jason Glenesk, Raul Rangel, Marshall Dawson, Matt DeVillier, Tim Wawrzynczak, Fred Reitberger, Karthik Ramasubramanian, Felix Held,

to look at the new patch set (#16).

Change subject: soc/amd: Add low/no battery mode to DPTC

soc/amd: Add low/no battery mode to DPTC

Update acpigen_write_alib_dptc() to support "low/no battery mode",
which throttles the SOC when there is no battery connected or the
battery charge is critically low.

This refactor CL is in preparation for enabling this functionality for
the Mendocino SOC.
