board: freescale: p1_p2_rdb_pc: Remove mapping for TDM-PMC card

From whole P1/P2 family of RDB boards is TDM-PMC card (PCI Mezzanine Card,
Freescale PQ-MDS-T1) available only on P1021RDB and P1025RDB boards.

So address mapping for TDM-PMC card on LBC should not be enabled on any
other P1/P2 RDB board as there is no device at that TDM-PMC address.

Support for P1021RDB and P1025RDB boards was already removed from mainline
U-Boot in commits 6d1dd76a ("board/freescale: Remove P1021RDB board
support") and d521cece ("board/freescale: Remove P1025RDB board
support").

So do not enable TDM-PMC address mapping on remaining P1/P2 RDB boards and
remove all macros related to TDM-PMC address mappings.
