Subject: [RFC PATCH 4/8] PNPACPI: remove unsupported serial PNP ids from PNPACPI id list

The "serial" pnp driver supports some unknown PNP modems (PNPCXXX/PNPDXXX)
by matching magic strings in the pnp device name or the pnp device card name.

ACPI enumerated PNP device neither supports pnp card,
nor supports those magic strings in its device name,
which means this mechamism never works for ACPI enumerated
PNPCXXX/PNPDXXX devices.
So it is safe to remove those two ids from the PNPACPI id list.
