Pass in tsec_info struct through tsec_initialize
The tsec driver contains a hard-coded array of configuration information for the tsec ethernet controllers. We create a default function that works for most tsecs, and allow that to be overridden by board code. It creates an array of tsec_info structures, which are then parsed by the corresponding driver instance to determine configuration. Also, add regs, miiregs, and devname fields to the tsec_info structure, so that we don't need the kludgy "index" parameter.
