[PATCH v1 1/1] include: configs: Adds support for AM335x ICE PRUSS mode

On the AM3359 ICE we have two modes of operation CPSW mode or PRU-ICSS
mode.

For PRU-ICSS mode, connect Pin2 and Pin3 of J18 and J19 and for CPSW mode,
connect Pin1 and Pin2 of J18 and J19.

This patch adds support for PRUSS mode boot strapping from uboot.
