[PATCH v5 4/8] drm/msm/dpu: make fix_core_ab_vote consistent with fix_core_ib_vote

[Dmitry Baryshkov]

The fix_core_ab_vote is an average bandwidth value, used for bandwidth
overrides in several cases. However there is an internal inconsistency:
fix_core_ib_vote is defined in KBps, while fix_core_ab_vote is defined
in Bps.

Fix that by changing the type of the variable to u32 and using * 1000ULL
multiplier when setting up the dpu_core_perf_params::bw_ctl value.
