Changes in v2:
- add comment from Stefano Babic:
- adapt for i2c fixes suggested by Stefano Babic
- remove lgdisplay var
- remove CONFIG_PHY_MICREL_KSZ9031
- rename enable_spi to enable_spi_display
- rotate logo remains in board code
Changes in v3:
- add comment from Stefano Babic:
merged aristainetos2 board with the aristainetos board support
introduced a include/configs/aristainetos-common.h for common
settings, board/aristainetos/aristainetos-v1.c and
board/aristainetos/aristainetos-v2.c for board version specific
settings
