arm: dts: ti: Add device tree support for PRU-ICSS on AM437x

The TI Sitara AM437x series of devices consists of 2 PRU-ICSS instances
(PRU-ICSS0 and PRU-ICSS1). This patch adds the device tree nodes for the
PRU-ICSS1 instance to support DUAL-MAC mode of operation. Support for
Ethernet over PRU is available only for ICSS1 instance.

PRU-ICSS instance consists of two PRU cores along with various
peripherals such as the Interrupt Controller (PRU_INTC), the Industrial
Ethernet Peripheral(IEP), the Real Time Media Independent Interface
controller (MII_RT), and the Enhanced Capture (eCAP) event module.

am4372.dtsi - Adds IEP and eCAP peripheral as child nodes of the PRUSS
subsystem node.

am437x-idk-evm.dts - Adds PRU-ICSS instance node along with PRU eth port
information and corresponding port configuration. It includes interrupt
mapping for packet reception, HW timestamp collection, and PRU Ethernet
ports in MII mode,

GPIO configuration, boot strapping along with delay configuration for
individual PRU Ethernet port and other required nodes.
