[PATCH] clocksource: acpi_pm: add another greylist chipset

[PATCH] clocksource: acpi_pm: add another greylist chipset

I have an acpi_pm that goes backwards, but it's not intel.  I tested the
verified read and my acpi_pm started to function properly.  So I added it
to the greylist.  I'm assuming that's the right spot.

I also added an unlikely() to the while, cause it seems appropriate.
