[PATCH v6 0/3] pnv nest1 chiplet model

[Chalapathi V]

Hello,

Thank you for the review and suggestions on V5.

The suggestions and changes requested from V5 are addressed in V6.

Updates in Version 6 of this series are: 
1. adding a device-tree node in QEMU is removed as skiboot defines the
   device-tree and QEMU should just follow it.
2. Renamed PnvPerv to PnvNestChipletPervasive in PATCH1 as the model provides
   the common pervasive registers of all nest chiplets.
3. Nest1_chiplet model in PATCH2 is renamed to N1_chiplet to avoid the
   confussions that may comeup later.

Hence the new qom-tree looks like below.
(qemu) info qom-tree 
/machine (powernv10-machine)
  /chip[0] (power10_v2.0-pnv-chip)
    /n1_chiplet (pnv-N1-chiplet)
      /nest_pervasive_common (pnv-nest-chiplet-pervasive)
        /xscom-n1_chiplet-control-regs[0] (memory-region)
      /xscom-n1_chiplet-pb-scom-eq-regs[0] (memory-region)
      /xscom-n1_chiplet-pb-scom-es-regs[0] (memory-region)

Patches overview in V6.
PATCH1: Create a common nest pervasive chiplet model with control chiplet scom
        registers.
PATCH2: Create a N1 chiplet model and implement powerbus scom registers.
        Connect common nest pervasive model to N1 chiplet model to define
        chiplet control scoms for N1 chiplet.
PATCH3: Connect N1 chiplet model to p10 chip.

Test covered:
These changes are tested on a single socket and 2 socket P10 machine.

Thank You,
Chalapathi
