ARM: dts: am437x-gp-evm: Enable PRU-ICSS nodes

The AM437x GP EVM board uses a AM437x SoC that supports two PRU-ICSS
instances. The PRU-ICSS processor bus nodes and subsystem nodes were
left in disabled state in the base am4372.dtsi file. All these nodes
(both PRU-ICSS1 and PRU-ICSS0 instances) have been enabled now. The
PRU nodes are already enabled in the base dts file, and so become
effective automatically with the enabling of these PRU-ICSS nodes.

The corresponding PRU nodes can be disabled later on if there are
no use-cases defined to use a particular PRU core or the whole
PRU-ICSS subsystem itself if both its PRU cores are unused.
