ata: ahci_platform: allow disabling of hotplug to save power
A number of resources remain powered to support hotplug. On platforms I've worked with, allowing the ahci_platform to suspend saves about 150mW. This patch enables rpm and allows the device to be auto-suspended through sysfs. Signed-off-by: Samuel Morris <samorris@lexmark.com> Signed-off-by: Tejun Heo <tj@kernel.org>
