[Why]
- DPIA MST slot registers are not programmed during payload
allocation and hence MST does not work with DPIA.
- HPD RX interrupts are not handled for DPIA.

[How]
- Added inbox command to program the MST slots whenever
  payload allocation happens for DPIA links.
- Added support for handling HPD RX interrupts

[Why]
DMUB binary is common for both A0 and B0. Hence, driver should
notify FW about the support for DPIA in B0.

[How]
Added dpia_supported bit in dmub_fw_boot_options and will be set
only for B0.

Assign dpia_supported to true before dm_dmub_hw_init
in B0 case.

[Why]
B0 has pipe mux for DIGC and DIGD which can be connected to PHYF/PHYG or
PHYC/PHY D.

[How]
Based on chip internal hardware revision id determine it is B0 and set
DMUB scratch register so DMUBFW can connect the display pipe is
connected correctly to the dig.
