f7d6fcf7ae dm: core: Add dev_read_enabled() to check if a device is enabled 
This function allows a device's status to be read. This indicates whether
the device should be enabled or disabled.

Note: In normal operation disabled devices will not be present in the
driver-model tree.

When the live tree is supported some functions need to change a little.
Add an implementation which is used when not inlining these functions.
