[MIPS] Rename Alchemy processor configs into CONFIG_SOC_*

CONFIG_SOC_AU1X00

  Common Alchemy Au1x00 stuff. All Alchemy processor based machines
  need to have this config as a system type specifier.

CONFIG_SOC_AU1000, CONFIG_SOC_AU1100, CONFIG_SOC_AU1200,
CONFIG_SOC_AU1500, CONFIG_SOC_AU1550

  Machine type specifiers. Each port should have one of aboves.
