arm64: dts: ti: k3-am62p-j722s-common-main: Add HSM M4F node

The TI K3 AM62P and J722S SoCs have a HSM (High Security Module) M4F
core in the MAIN Voltage Domain which could be used to run secure
services like Authentication. Add Device Tree Node definitions for the
HSM core in the respective SoC common main dtsi file.

The HSM node is reserved to be loaded and booted by the early-stage
bootloader. The firmware-name property is defined at the SoC level
since the HSM is not a general-purpose remote core and boards are
unlikely to use separate firmware. If needed in exceptional cases,
board-specific device trees can override this property.

The corresponding reg ranges of HSM node has also been added to its
parent node's (cbass_main bus) ranges property.
