[PATCH v2 4/4] arm: dts: omap4-sdp: add WiLink7 device tree node

[Luciano Coelho]

Add appropriate device tree node for Blaze's WiLink7 module.  It uses
a GPIO as interrupt, so configure the gpio2 node as interrupt parent
and assign the corresponding GPIO.  Additionally, add the clock
frequencies used by the module.
