All Alchemy development boards (except the PB1000) have external CPLDs with a few registers in them. They all share an identical register layout with only a few minor differences in bit functions and base addresses. This is useful for drivers which can work across the whole range of boards (e.g. the PCMCIA socket driver). This patch adds a primitive facility to initialize and use these external registers and replaces all occurrences of bcsr->xxx accesses with calls to the new functions (except for the PB1200 IRQ cascade, which doesn't work with it). Run-tested on the DB1200, as far as possible.
