MIPS: Alchemy: remove cpu_table.

Remove the cpu_table:
- move detection of whether c0_config[OD] is read-only and should be set
  to fix various chip errata to au1000 headers.
- move detection of write-only sys_cpupll to au1000 headers.
- remove the BCLK switching code:  Activation of this features should be
  left to the boards using the chips since it also affects external devices
  tied to BCLK, and only the board designers know whether it is safe to
  enable.
