hwc: Program default mode upon boot anim completion

Default display mode needs to applied exactly on boot
completion. Hence we check for the exact instance of
boot completion by checking the property of boot
animation exit. We keep on checking till the property
is found to be set and program the default mode over
a dynamic link to libmm-qdcm.so
