overo: add SPL support
* implementation based on ti beagleboard/omap3evm * timing data and i2c workaround for revision 0 boards taken from x-loader * run-tested with overo revision 0 and 1 / boot from NAND and SDcard * run-tested with x-loader Signed-off-by: Andreas Müller <schnitzeltony@gmx.de> Signed-off-by: Tom Rini <trini@ti.com>
