[ARM] nommu: manage the CP15 things

All the current CP15 access codes in ARM arch can be categorized and
conditioned by the defines as follows:

     Related operation Safe condition
  a. any CP15 access !CPU_CP15
  b. alignment trap CPU_CP15_MMU
  c. D-cache(C-bit) CPU_CP15
  d. I-cache CPU_CP15 && !( CPU_ARM610 || CPU_ARM710 ||
CPU_ARM720 || CPU_ARM740 ||
CPU_XSCALE || CPU_XSC3 )
  e. alternate vector CPU_CP15 && !CPU_ARM740
  f. TTB CPU_CP15_MMU
  g. Domain CPU_CP15_MMU
  h. FSR/FAR CPU_CP15_MMU

For example, alternate vector is supported if and only if
"CPU_CP15 && !CPU_ARM740" is satisfied.
