[PATCH v2 0/8] Add mode2 reset support for aldebaran

[Lazar, Lijo]

[AMD Public Use]

This patch series adds support for mode2 reset for aldebaran. Since the
reset sequence is completely different from existing ones, it adds
supports using a new reset control method. The reset control and
handlers can be installed and handle specific types of resets.

v1:
1. Changes to the mode2 sequence as PCI space gets lost during the
sequence.
2. Add support to wait for specific events from PMFW. Reset complete is
considered as one such event.
3. Add support to wait for reset completion on aldebaran
4. Add a new reset control and reset handler method. Reset control can
be installed at device, hive or ip level. For now, it's done only at
device level
5. Add reset control mechanism to the current recover sequence.
6. Expose PSP function to load a list of firmwares
7. Expose CG/PG set functions for use outside of device
8. Add mode2 reset and restore sequences for aldebaran.

v2:
- Coding style fixes
- Mutex protection for new smu api (#2)
- Clear bus mastering before reset (#8)
