Subject: [PATCH 0/2] platform/x86: ideapad-laptop: Add charge_types:Fast (Rapid Charge)

The GBMD/SBMC interface on IdeaPad/ThinkBook supports Rapid Charge mode
(charge_types: Fast) in addition to Conservation Mode (charge_types:
Long_Life).

This patchset exposes these two modes while carefully maintaining their
mutually exclusive state, which aligns with the behavior of manufacturer
utilities on Windows.

Tested on ThinkBook 14 G7+ ASP.
