libata-sff: Don't scan disabled ports when checking for legacy mode.
libata-sff.c checks for legacy mode by testing if both primary and
secondary ports on a controller are in legacy mode and selects legacy
if either one is. However on some south bridge chips (e.g AMD
SB600/SB700) the secondary port is not wired, and when it is disabled
by setting the disable bit in the PCI header it appears as a fixed
legacy port.
Prevent incorrect detection by not testing ports that are marked as
'dummy'
tj: Addressed Sergei's review points. Other style edits.
