[U-Boot] [PATCH v3 03/35] dm: core: Add dev_read_enabled() to check if a device is enabled

[sjg at google.com]

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.
