e160f7d430 dm: core: Replace of_offset with accessor
At present devices use a simple integer offset to record the device tree
node associated with the device. In preparation for supporting a live
device tree, which uses a node pointer instead, refactor existing code to
access this field through an inline function.

6a436c9182 dm: led: Tidy up SPL options for the led and led-gpio
At present SPL does not have its own option. But these features can
increase SPL code size. Adjust the Kconfig and Makefile so that
separate a SPL option can be selected.

0b11dbf705 drivers: hierarchize drivers Kconfig menu
The menuconfig for drivers are getting more and more cluttered
and unreadable because too many entries are displayed in a single
flat menu.  Use hierarchic menu for each category.

fb8a5ffc77 led: Return -ENODEV if the LED device cannot be found
We normally use -ENODEV for a missing device, rather than -ENOENT. The
latter is reserved for when we have a device but cannot find something
within it.

Also avoid looking at the root LED device since it is only a container.

5ac76bad22 dm: led: Add a driver for GPIO-controlled LEDs
Add a simple driver which allows use of LEDs attached to GPIOs. The linux
device tree binding is used.

5917112c9e dm: Add support for LEDs
Add a simple uclass for LEDs, so that these can be controlled by the device
tree and activated when needed. LEDs are referred to by their label.

This implementation requires a driver for each type of LED (e.g GPIO, I2C).
