soc/amd/cezanne: add partial data fabric setup

I'm not 100% sure yet if this code will be common for all AMD SoCs, so
I'll add a copy for Cezanne for now. This part of the code should
probably be reworked after the initial bringup of Cezanne anyway.

DF MMIO register configuration at the beginning of
data_fabric_set_mmio_np:

=== Data Fabric MMIO configuration registers ===
Addresses are shifted to the right by 16 bits.
idx  control     base    limit
  0       a3     fc00     febf
  1       a3  1000000 fffcffff
  2       a3     d000     f7ff
  3       a0        0        0
  4       a3     fed0     fed0
  5       a0        0        0
  6       a0        0        0
  7       a0        0        0
