There are some platforms that don't have a dedicated GPIO line to manage the AC/DC switch. In this case, the SI SMC automatically notices when switching to DC, but needs to be notified when switching to AC. Fixup and use si_notify_hw_of_powersource() which was previously hidden behind an "#if 0". This fixes some SI laptop GPUs to be able to use their performance power states after switching from DC to AC. Some affected GPUs are: FirePro W4170M - Dell Precision M2800 Radeon HD 8790M - Dell Latitude E6540 Reviewed-by: Alex Deucher <alexander.deucher@amd.com> Co-developed-by: Timur Kristóf <timur.kristof@gmail.com> Signed-off-by: Timur Kristóf <timur.kristof@gmail.com> Signed-off-by: Jeremy Klarenbeek <jeremy.klarenbeek99@gmail.com> Signed-off-by: Alex Deucher <alexander.deucher@amd.com>
