ppc/pnv: Fix OCC common area region mapping
The OCC common area is mapped at a unique address on the system and
each OCC is assigned a segment to expose its sensor data :
-------------------------------------------------------------------------
| Start (Offset from | End | Size |Description |
| BAR2 base address) | | | |
-------------------------------------------------------------------------
| 0x00580000 | 0x005A57FF |150kB |OCC 0 Sensor Data Block|
| 0x005A5800 | 0x005CAFFF |150kB |OCC 1 Sensor Data Block|
| : | : | : | : |
| 0x00686800 | 0x006ABFFF |150kB |OCC 7 Sensor Data Block|
| 0x006AC000 | 0x006FFFFF |336kB |Reserved |
-------------------------------------------------------------------------
Maximum size is 1.5MB.
We could define a "OCC common area" memory region at the machine level
and sub regions for each OCC. But it adds some extra complexity to the
models. Fix the current layout with a simpler model.
