[PATCH 51/61] PCI: Remove quirk_via_abnormal_poweroff

[Chris Wright]

-stable review patch.  If anyone has any objections, please let us know.
------------------

From: Karsten Wiese <annabellesgarden@xxxxxxxx>

My K8T800 mobo resumes fine from suspend to ram with and without patch
applied against 2.6.18.

quirk_via_abnormal_poweroff makes some boards not boot 2.6.18, so IMO patch
should go to head, 2.6.18.2 and everywhere "ACPI: ACPICA 20060623" has been
applied.


Remove quirk_via_abnormal_poweroff

Obsoleted by "ACPI: ACPICA 20060623":
<snip>
    Implemented support for "ignored" bits in the ACPI
    registers.  According to the ACPI specification, these
    bits should be preserved when writing the registers via
    a read/modify/write cycle. There are 3 bits preserved
    in this manner: PM1_CONTROL[0] (SCI_EN), PM1_CONTROL[9],
    and PM1_STATUS[11].
