ClearwaterForest has CPUID 0x1f by default, so force enabling this leaf
for it (ClearwaterForect-v3).

And add the cache model to ClearwaterForest (v3) to better emulate its
environment.

The cache model is based on ClearwaterForest-AP (Advanced Performance):

      --- cache 0 ---
      cache type                         = data cache (1)
      cache level                        = 0x1 (1)
      self-initializing cache level      = true
      fully associative cache            = false
      maximum IDs for CPUs sharing cache = 0x0 (0)
      maximum IDs for cores in pkg       = 0x3f (63)
      system coherency line size         = 0x40 (64)
      physical line partitions           = 0x1 (1)
      ways of associativity              = 0x8 (8)
      number of sets                     = 0x40 (64)
      WBINVD/INVD acts on lower caches   = false
      inclusive to lower caches          = false
      complex cache indexing             = false
      number of sets (s)                 = 64
