drm/amd/display: Improve logic for is_lttpr_present
[WHY]
DP specifies that an LTTPR device is only present if PHY_REPEATER_CNT is
0x80, 0x40, 0x20, 0x10, 0x08, 0x04, 0x02, or 0x01.
All other values should be considered no LTTPRs present.
[HOW]
Function dp_convert_to_count already does this check. Use it to determine
if PHY_REPEATER_CNT is a valid LTTPR count.
