David Milburn 1757d902b0 libata: export host controller number thru /sys 
As low-level drivers register their host controller(s), keep track
of the number of controllers and export thru /sys in a <host.port>
format so that udev can better match up port numbers with a
specific controller.

# pwd
/sys/devices/pci0000:00
# find . -name 'ata*' -print

(2nd controller with port multiplier attached)
