msm_fb: Remove the extra freelist in display_commit

There is an extra freelist call to unmap IOMMU source buffers
in display_commit for LCDC interface. This is causing IOMMU
page faults during boot up on targets with LCDC interfaces.
Remove this extra freelist call.

msm_fb: display: Do a pre-fill to writeback buffers.

When switching mdp operating mode to blt, writeback buffers need
pre-fill. Move the pre-fill code from isr routine to do_blt, where
actual switch to blt mode happens.

msm_fb: display: fix the hang issue caused by solidfill pipe

When mdp pipe solidfill mode is disabled, the staled pipe info is used
to update mdp pipe regs. This caused mdp hang. Since
mdp4_overlay_rgb_setup function already resets solidfill mode, this
patch removes any pipe register updates that are related to disabling
solidfill mode.

scenario.
