MIPS: Alchemy: devboards: wire up new PCMCIA driver.
Register the PCMCIA driver on all boards supported by it, get rid of now-unused pcmcia macros in the board headers (and subsequently empty pb1100/pb1500 ones). Signed-off-by: Manuel Lauss <manuel.lauss@gmail.com> Signed-off-by: Ralf Baechle <ralf@linux-mips.org>
