95a437966d MIPS: Alchemy: devboards: factor out PB1200 IRQ cascade code. 
Move the PB1200 IRQ cascade code out to the BCSR support code:
upcoming DB1300 support can use it too.

9bdcf336d0 MIPS: Alchemy: devboard register abstraction 
All Alchemy development boards have external CPLDs with a few registers
in them.  They all share an identical register layout with only a few
minor differences (except the PB1000) in bit functions and base
addresses.

This patch
- adds a primitive facility to initialize and use these external
  registers,
- replaces all occurrences of bcsr->xxx accesses with calls to the new
  functions (the pb1200 cascade irq handling code is special).
- collects BCSR register information scattered throughout the board
  headers in a central place.
