Subject: drm/msm/dp: Drop now unused hpd_high member
Git-commit: fabae667b1263216be53e0230cd3966a9a1963a4
Patch-mainline: v5.17-rc1
References: jsc#PED-1166 jsc#PED-1168 jsc#PED-1170 jsc#PED-1218 jsc#PED-1220 jsc#PED-1222 jsc#PED-1223 jsc#PED-1225
Since '8ede2ecc3e5e ("drm/msm/dp: Add DP compliance tests on Snapdragon
Chipsets")' the hpd_high member of struct dp_usbpd has been write-only.
Let's clean up the code a little bit by removing the writes as well.
