pata_cm64x: fix boot crash on parisc
The old IDE cmd64x checks the status of the CNTRL register to see if the ports are enabled before probing them. pata_cmd64x doesn't do this, which causes a HPMC on parisc when it tries to poke at the secondary port because apparently the BAR isn't wired up (and a non-responding piece of memory causes a HPMC). Fix this by porting the CNTRL register port detection logic from IDE cmd64x. In addition, following converns from Alan Cox, add a check to see if a mobility electronics bridge is the immediate parent and forgo the check if it is (prevents problems on hotplug controllers).
