ARM: pxafb: Fix access to nonexistent member of pxafb_info

Browse Source 
In case CONFIG_FB_PXA_OVERLAY is not defined, the pxafb_freq_transition()
function tests nonexistent member of pxafb_info (since the member is not
part of the structure).

Fix this by wraping the test in ifdef, even if I don't really like how the code
looks now. The check doesn't have to happen if overlays are disabled at all as
the check is always true then.
