OMAP4: Initialise the l3 device with the hwmod data.

The l3 interconnect device is build with all the data required to handle the error logging. The data is extracted from the hwmod data base. Signed-off-by: Santosh Shilimkar <santosh.shilimkar@ti.com> Signed-off-by: sricharan <r.sricharan@ti.com> Acked-by: Benoit Cousson <b-cousson@ti.com>
