debug ata: Distinguish between Advanced power management and basic PM

Browse source 
The old debug menu item covered APM, which is optional in the ATA spec
However, despite basic power management being mandatory, several popular
ATA/CF->SD adapters do not advertise PM support and have problems when
it is used.

An earlier patch (g#2500 / 5462907) disabled sleep when the PM
capability bit was not set; this makes it visible in the debug menu.
