In general disabling the unused devices by default for omaps will break
the power management. The disabled devices are completely ignored by the
kernel, and the devices are left to whatever the bootloader state might
be.

For SoCs using firmware to manage devices it's a bit different story
however. The firmware can still idle disabled devices based on a
late_initcall for example, even if the kernel knows nothing about the
disabled devices.
