parport: parport_pc: Implement architecture and device check to cut off false-positives
We definitely know that only x86 (32-bit) architecture is affected by the issue, so implement a stub instead of the actual check for other architectures. We also know that motherboard LPT chipset is affected, so the port is either come from parport_pc_init (when `io' module param is used) or parport_pc_find_isa_ports (when default LPT ports are probbed: 0x378, 0x278, 0x3bc). In both cases the port considered as 'legacy' and `dev' member of struct parport is NULL. See also comments for `struct parport' in parport.h Signed-off-by: Matwey V.
