Subject: [BUG] [Gigabyte GA-MA78GPM-DS2H] ACPI wakeup fails if HPET enabled
in BIOS
[Full Description]
If I enable HPET in BIOS on Gigabyte GA-MA78GPM-DS2H (AMD 780G chipset)
and I try to set up ACPI wakeup using (as root):
echo `date '+%s' -d '+ 5 minutes'` > /sys/class/rtc/rtc0/wakealarm
or:
rtcwake -d rtc0 -u -m no -t `date '+%s' -d '+ 5 minutes'`
The computer does not wake up.

drivers/rtc/rtc-cmos.c: don't disable hpet emulation on suspend
BugLink: http://bugs.launchpad.net/bugs/1178361
<http://bugs.launchpad.net/bugs/1178361>
commit e005715efaf674660ae59af83b13822567e3a758 upstream.
There's a bug where rtc alarms are ignored after the rtc cmos suspends
but before the system finishes suspend. Since hpet emulation is
disabled and it still handles the interrupts, a wake event is never
registered which is done from the rtc layer.
This patch reverts commit d1b2efa83fbf ("rtc: disable hpet emulation on
suspend") which disabled hpet emulation. To fix the problem mentioned
in that commit, hpet_rtc_timer_init() is called directly on resume.
