[U-Boot] [PATCH 6/8] [omap3][overo] Add Board Revision for Wireless chip

[Ash Charles <ashcharles@gmail.com>]

Gumstix Overo COMs with board revision 0x4 use a different Wifi and
Bluetooth module: Wi2Wi's W2CBW0015.  No other code changes are required
in u-boot---just handling of this particular board revision.
