x86: acpi: workaround Windows not handling name references in Package…

… properly

it seems that Windows is unable to handle variable references
making it choke up when accessing ASUN during _DSM call
when device is hotplugged (it lists package elements as DataAlias
but despite that later on it misbehaves) with following error
shown up in AMLI debugger (WS2012r2):
    Store(ShiftLeft(One,Arg1="ASUN",) AMLI_ERROR(c0140008): Unexpected argument type
    ValidateArgTypes: expected Arg1 to be type Integer (Type=String)
Similar outcome with WS2022.

Issue is not fatal but as result acpi-index/"PCI Label ID" property
is either not shown in device details page or shows incorrect value.

Fix it by doing assignment of BSEL/ASUN values to package
elements manually after package declaration.

Fix was tested with: WS2012r2, WS2022, RHEL9
