Subject: [PATCH] ata: sata_mv: add proper definitions for LP_PHY_CTL register
 values

Commit 9013d64e661fc ("ata: sata_mv: fix disk hotplug for Armada
370/XP SoCs") added some manipulation of the LP_PHY_CTL register, but
using magic values. This commit changes the code to use proper
definitions for the LP_PHY_CTL register, which allows to document what
the different bits are doing.
