[U-Boot] [PATCH] driver: net: ldpaa_eth: Get MAC address from env variable

[Prabhakar Kushwaha]

Currently ldpaa ethernet driver rely on DPL file to statically configure
mac address for the DPNIs. It is not a correct approach.

Add support of reading MAC address for env variable and configure same
in DPAA driver.
