Previous version of patch was line wrapped and had some style issues. 
correcting it.

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.This patch will 
add
gpio_macros as well which is required for resetting phy
