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.

-/* The tsec_info structure contains 3 values which the
- * driver uses to determine how to operate a given ethernet
- * device. The information needed is:
- * phyaddr - The address of the PHY which is attached to
- * the given device.
- *
- * flags - This variable indicates whether the device
- * supports gigabit speed ethernet, and whether it should be
- * in reduced mode.
- *
- * phyregidx - This variable specifies which ethernet device
- * controls the MII Management registers which are connected
- * to the PHY. For now, only TSEC1 (index 0) has
- * access to the PHYs, so all of the entries have "0".
- *
- * The values specified in the table are taken from the board's
- * config file in include/configs/. When implementing a new
- * board with ethernet capability, it is necessary to define:
- * TSECn_PHY_ADDR
- * TSECn_PHYIDX
- *
- * for n = 1,2,3, etc. And for FEC:
- * FEC_PHY_ADDR
- * FEC_PHYIDX
