[09/11] ARM: dts: omap3-igep0020-rev-f: Support IGEPv2 Rev. F

Commit Message

Add support for the new hardware revision of the IGEPv2. Basically, the new
revision F replaces the old Wifi module for a Wilink8 based module.

I wonder if now that you added the omap3-igep00{2,3}0-common.dtsi
files, it could make sense to add support for all the different
variations of IGEPv2 and IGEP COM Modules using both NAND and OneNAND
flash memories.

But that is a question unrelated to this patch so for $subject:
