Add configuration files/dtses for mini u-boot configuration which runs on smaller footprint of internal memory. This configuration has only required qspi flash support and it uses DCC as serial.

Signed-off-by: Siva Durga Prasad Paladugu siva.durga.paladugu@xilinx.com

Chnages for v2:

• Fixed copyright year
• Fixed memory node
• Removed partitions in flash node
• Moved CONFIG_MP to kconfig

This patch is based on https://lists.denx.de/pipermail/u-boot/2018-July/335126.html

Applied.
