Subject: drm/msm/dpu: remove dpu_mdss:hwversion
Git-commit: 1569fcd7555e03084eae670721cd8afe60a53211
Patch-mainline: v5.4-rc1
References: bsc#1152489

Unused and the extra rpm get/put interferes with handover from
bootloader (ie. happens before we have a chance to check if
things are already enabled).
