[U-Boot] [U-boot] [PATCH 1/2] NET: QE: UEC: Make uec_miiphy_read() and uec_miiphy_write() use the devname arg.

[richardretanubun <richardretanubun@ruggedcom.com>]

Added a new function uec_miiphy_find_dev_by_name to allow uec_miiphy_read 
and uec_miiphy_write to use the passed devname and not hardcoded to devlist[0]
