spmi: pmic_arb: add support for hw version 2
Qualcomm PMIC Arbiter version-2 changes from version-1 are:
- Some different register offsets.
- New channel register space, one per PMIC peripheral (ppid).
All tx traffic uses these channels.
- New observer register space. All rx trafic uses this space.
- Different command format for spmi command registers.
