From: Isaku Yamahata <isaku.yamah...@intel.com>
Commit 6be8cf56bc8b made sure that SCI is enabled in PM1.CNT
on reset in acpi_only mode by modifying acpi_pm1_cnt_reset() and
that worked for q35 as expected.
This patch adds reset ACPI PM related registers on vt82c686 reset time
and de-assert sci.
via_pm_realize() initializes acpi pm tmr, evt, cnt and gpe.
Reset them on device reset.
