[PATCH] libata: clear only affected flags during ata_dev_configure()
ata_dev_configure() should not clear dynamic device flags determined
elsewhere. Lower eight bits are reserved for feature flags, define
ATA_DFLAG_CFG_MASK and clear only those bits before configuring
device. Without this patch, ATA_DFLAG_PIO gets turned off during
revalidation making PIO mode unuseable.
