[Skiboot] [PATCH 29/61] platform: Add Denali platform support

[Vasant Hegde]

Denali is P10 system. But FSP interaction (MBOX protocol) is same as ZZ.
Hence add denali platform detection code inside zz.c for now. We can think
of adding separate platform later.

Also enable :
  - P10 TCE mapping support
  - Detect PHBs
