agesa/hudson/southbridge: add acpi name reporting for lpc

Add an lpc_acpi_name function to report its namespace as "LIBR"
rather than some fallback value which seems to vary. This repair
is required for the LPC TPM device to register its presence
without blowing up the table and preventing the payload from
seeing the SATA device.

Before change (but after other similar change to PCI0), the
TPM device reported itself as:

\_SB.PCI0.LPC0.TPM

After change, the TPM device reports as:

\_SB.PCI0.LIBR.TPM

which is consistent with the tables AGESA generates.
