[PATCH] ahci: Use dev_info() to inform about the lack of Device Sleep support

[Gabriele Mazzotta]

According to the Serial ATA AHCI specification, Device Sleep is an
optional feature and as such no errors should be printed if it's
missing. Keep informing users, but use dev_info() instead of dev_err().
