Public bug reported:

The xgene-ahci driver sets sets the sata phy configuration, but this
configuration can vary across platforms. Today the values we are using
are optimal for the mustang development board, but suboptimal for other
platforms. In general the recommendation is to move this into platform
specific config in firmware - either by having firmware do the phy
config, or by passing settings to the driver via device-tree config.
But, that's a long term solution - in the short term, we can special
case the Mustang board and use better default settings for other boards.
