[PATCH] arm: dts: am335x-bone-common.dtsi: add eeprom device to DT

[marc]

From: Marc Reilly <marc@cpdesign.com.au>

This adds a device node to provide support for the onboard eeprom of
beaglebone products. The eeprom contents can be used to determine the
type of beaglebone running. For example this can be used to
differentiate between the original Beaglebone Black and the wireless
version.

I see this node is present in the upstream dtsi in
dts/src/arm/am335x-bone-common.dtsi already. Maybe a better approach
would be to switch to the upstream file?
