[U-Boot] [PATCH v3 2/2] Enable test case with A20-OLinuXino-Lime2

[Stefan Mavrodiev]

Driver testing is done with A20-OLinuXino-Lime2. Testing
requirements are:
  - Exposing spi0 alternative pins in the dts file
  - Add alias node, enabling driver probing
  - Enable spi flash related options in the defconfig file

The testing log is:
