mms_fb: display: init pipe default configure as solidfill

Initialize mdp pipes default config as solid fill so that
there will have no memory fetch if pipe are staged into
mixer while flush bits are left behind and set at next vsync.
This is will prevent mdp iommu page fault from happening
at address 0x00000000 during resume.
