qe: Pass in uec_info struct through uec_initialize

The uec driver contains code to hard code configuration information for the uec
ethernet controllers. This patch creates an array of uec_info structures, which
are then parsed by the corresponding driver instance to determine configuration.
It also creates function uec_standard_init() to initialize all UEC interfaces
for 83xx and 85xx.
