BB retimer: Add condition to set 'DP CONNECTION' bit
Set 'DP CONNECTION' bit when mux_state gets HPD event only on
the ports with HDMI/DP card
It will increase BBR power consumption, so set 'DP CONNECTION'
bit only when mux_state gets HPD event only on the ports with
HDMI/DP card.
BUG=b:233975818
BRANCH=None
TEST=Test on Banshee, when only hdmi card 'DP CONNECTION' bit
is 0. Enter console command bb 1 r 4 =0x403, plug in hdmi
monitor bb 1 r 4 =0x8503.
Run ./twister -T zephyr/test/drivers
