[U-Boot] [PATCH] ARM: OMAP5: DRA7xx: Enable I2C4 and I2C5 usage on the J6Eco EVM

[Lubomir Popov]

On the J6Eco EVM we have two on-board devices on the I2C5 bus; this
bus is also routed to the camera and expansion connectors. I2C4 is
routed to one of the expansion connectors. This patch enables usage
of these two buses.

For I2C5 to work, the 'ARM: OMAP5: DRA7xx: Enable I2C5 operation'
patch is required as a prerequisite.

Tested on a J6 ECO EVM rev.B with a DRA726 ES1.0.
