drm/msm/dp: add support of tps4 (training pattern 4) for HBR3
Some DP sinkers prefer to use tps4 instead of tps3 during training #2.
This patch will use tps4 to perform link training #2 if sinker's DPCD
supports it.
Changes in V2:
-- replace dp_catalog_ctrl_set_pattern() with dp_catalog_ctrl_set_pattern_state_bit()
Changes in V3:
-- change state_ctrl_bits type to u32 and pattern type to u8
Changes in V4:
-- align } else if { and } else {
Changes in v10:
-- group into one series
Changes in v11:
-- drop drm/msm/dp: dp_link_parse_sink_count() return immediately if aux read
