From: Aleksei Mamlin <mamlinav@...il.com>

commit 08c85d2a599d967ede38a847f5594447b6100642 upstream.

Enabling AA on HP 250GB SATA disk VB0250EAVER causes errors:

[    3.789243] ata3.00: failed to enable AA (error_mask=0x1)

Add the ATA_HORKAGE_BROKEN_FPDMA_AA for this specific harddisk.

tj: Collected FPDMA_AA entries and updated comment.
