OMAP3: Add SMSC9221 device tree for omap devices connected on GPMC.

Browse Source 
Some OMAP3 devices support an SMSC ethernet PHY connected to the GPMC bus.
This copies this device tree from Linux 4.9.y stable

/*
* Common file for GPMC connected smsc9221 on omaps
*
* Compared to smsc911x, smsc9221 (and others like smsc9217
* or smsc 9218) has faster timings, leading to higher
* bandwidth.
*
* Note that the board specifc DTS file needs to specify
* ranges, pinctrl, reg, interrupt parent and interrupts.
