MIPS: MSP71xx: Platform support for On-chip MSP ethernet devices.

Some of MSP family SoC's come with legacy 100Mbps mspeth while some comes
with newer Gigabit TSMAC.Following patch adds platform support for both
types of MAC's.
If TSMAC is not selected assume platform having legacy mspeth.  Add
gpio_macros as well which is required for resetting the PHY.

[Ralf: Killed all typedefs.]
