Subject: drm/msm/hdmi: fill the pwr_regs bulk regulators
Git-commit: a18a44e9262d5c7f7fbccbc9458df64d69185d41
Patch-mainline: v6.0-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 jsc#PED-2849
Conversion to use bulk regulator API omitted filling the pwr_regs with
proper regulator IDs. This was left unnoticed, since none of my testing
platforms has used the pwr_regs. Fix this by propagating regulator ids
properly.
