ENGR00170145-1 ipuv3: add resource for overlay fb buffer reservation

We have already had framebuffer reservation for BG display
by set the base/size resource in fb platform data.
But we may also have FG fb buffer reserve requirement.
So add addtional base/size resource in fb plaform data,
add a IORESROUCE_MEM resource when fb device register
to meet such requirement.
