ARM: pxafb: Fix access to nonexistent member of pxafb_info
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.
