drm/amd/display: Fix minor issues in BW Allocation Phase2
[ Upstream commit aa5dc05340eb97486a631ce6bccb8d020bf6b56b ]
[Why]
Fix minor issues in BW Allocation Phase2.
[How]
- In set_usb4_req_bw_req(), link->dpia_bw_alloc_config.response_ready
flag should be reset before writing DPCD REQUEST_BW.
- Fix the granularity for value of 2 in get_bw_granularity().
- Removed bandwidth allocation support display fw boot option as
the fw would read feature enable status from bios.
- Clean up DPIA_EST_BW_CHANGED and DPIA_BW_REQ_SUCCESS cases in
dpia_handle_bw_alloc_response().
- Removed allocate_usb4_bw and deallocate_usb4_bw.
- Optimized loop in get_lowest_dpia_index().
- Updated link_dp_dpia_allocate_usb4_bandwidth_for_stream() and
set_usb4_req_bw_req() to always issue request bw.
