The pinmux for LED3 and LED4 are incorrectly attached to the
omap3_pmx_core when they should be connected to the omap3_pmx_wkup
pin mux.  This was likely masked by the fact that the bootloader
used to do all the pinmuxing.

V2:  Use current device tree naming convention for led-pins

This likely will require a separate patch to apply to previous file location.

The Ethernet PHY interrupt pin is routed to GPIO_58.  Create a
PHY node to configure this GPIO for the interrupt to avoid polling.
