Subject: ata: pmp: add quirk for Marvell 4140 SATA PMP
From: Lior Amsalem <alior@xxxxxxxxxxx>
commit 945b47441d83d2392ac9f984e0267ad521f24268 upstream.
This commit adds the necessary quirk to make the Marvell 4140 SATA PMP
work properly. This PMP doesn't like SRST on port number 4 (the host
port) so this commit marks this port as not supporting SRST.
