parport_pc: Let chipset drivers mask unsupported modes

Rename `parport_pc_probe_port' to `__parport_pc_probe_port' and add a
`mode_mask' parameter so that callers can specify a mask of unsupported
modes to exclude even if mode probing seems to indicate otherwise.  Add
a `parport_pc_probe_port' wrapper with an implicit mask of 0 for the
current callers to use.

No functional change at this point, but the configuration of data write
handlers is now no longer intertwined with determination and reporting
of available modes.
