libata: set NODEV_HINT for 0x7f status
Asus Pundit-R with atiixp controller has the second port missing and, very unusually, its status is stuck at 0x7f and all others at 0. This meanst that it fails TF access test but gets detected as a disk due to classification code check and then evades polling IDENTIFY presence detection thanks to the missing BSY in the status value causing excessive delays during boot. This patch makes libata-sff HSM set NODEV_HINT if the status is 0x7f to make polling IDENTIFY presence detection work for these machines.
