There has been an LED framework in U-Boot which uses driver model for
about 9 years now. Recent work is underway to improve it and provide
more features. It is probably a good time to drop the old code, which
is only used by 5 boards:

   ./tools/qconfig.py -f LED_STATUS
   5 matches
   eb_cpu5282 eb_cpu5282_internal mx23_olinuxino pinephone
   socfpga_vining_fpga

This series attempts that.

The new /options node provides a way to provide U-Boot settings, and
LEDs are implemented there. For now I have brought into the options
schema from upstream. We can update it once the LED additions land
there.

Changes in v3:
- Update commit message
- Combine removal and enable patches
- Combine removal and enable patches
- Combine removal and enable patches

Changes in v2:
- Combine code-removal and defconfig changes
- Add a patch to enable LED and LED_BOOT for these boards
- Enable LED on the 5 affected platforms
- Reorder patches for bisectability
- Add dt-schema bindings for LED
