Commit b4bc9f9e27ed ("cpufreq: ti-cpufreq: add support for omap34xx
and omap36xx") introduced special handling for OMAP3 class devices
where syscon node may not be present. However, this also creates a bug
where the syscon node is present, however the offset used to read
is beyond the syscon defined range.

Fix this by providing a quirk option that is populated when such
special handling is required. This allows proper failure for all other
platforms when the syscon node and efuse offsets are mismatched.
