drm/i915/fbc: Bump ivb FBC max surface size to 4kx4k

Browse Source 
IVB Bspec says:
"Frame Buffer Compression is only supported with memory surfaces of 4096 lines
or less and pipe source sizes of 4096 pixels by 2048 lines or less. "

so seems like we should be able to bump the offset+size limit to
at least 4kx4k. Make it so.
