MIPS: PCMCIA: new socket driver for Au1000 demoboards.
New PCMCIA socket driver for all Db/Pb1xxx boards (except Pb1000),
which replaces au1000_db1x00.c and (most of) au1000_pb1x00.c.
Notable improvements:
- supports Db1000, DB/PB1100/1500/1550/1200.
- support for carddetect and statuschange IRQs.
- pcmcia socket mem/io/attr areas and irqs passed through
platform resource information.
- doesn't freeze system during card insertion/ejection like
the one it replaces.
- boardtype is automatically detected using BCSR ID register.
Run-tested on the DB1200.
