ACPI, APEI, Resolve false conflict between ACPI NVS and APEI

ACPI, APEI, Resolve false conflict between ACPI NVS and APEI

Some firmware will access memory in ACPI NVS region via APEI.  That
is, instructions in APEI ERST/EINJ table will read/write ACPI NVS
region.  The original resource conflict checking in APEI code will
check memory/ioport accessed by APEI via general resource management
mech.  But ACPI NVS region is marked as busy already, so that the
false resource conflict will prevent APEI ERST/EINJ to work.

To fix this, this patch excludes ACPI NVS regions when APEI components
request resources.  So that they will not conflict with ACPI NVS
regions.
