OMAP3: Overo: Update GPMC timing for ethernet chip
The existing timing does not quite meet the minimum requirements in the LAN9221 datasheet. The timing in this patch solves problems noticed on some parts. The patch also combines the CS configuration for the overo and igep0020 boards per request. Signed-off-by: Philip Balister <philip@opensdr.com> Signed-off-by: Sandeep Paulraj <s-paulraj@ti.com>
