[U-Boot] [U-boot] [PATCH 2/2] NET: QE: UEC: Allow uec re-initialization based on netretry environment variable.

[richardretanubun <richardretanubun@ruggedcom.com>]

Allow uec_init to run more than once, based on the netretry environment 
variable.
This allows for manual (back and forth) switching between network 
interfaces.
