media: mali-c55: Bypass Purple Fringe Correction

The Purple Fringe Correction module is enabled by default with a POR
configuration which might not be correct for the lens/sensor combination
in use.

If the Purple Fringe Correction module has to be used, it needs to be
supported in the driver's uAPI and properly configured by userspace.

As the driver doesn't support it at the moment, bypass it by default.
