ata: pmp: add quirk for Marvell 4140 SATA PMP

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.
