[PATCH v4 09/11] arm: dts: k3-{j721s2/j722s/j784s4}-r5.dtsi: Enable HSM core

[Beleswar Padhi]

The HSM M4F node is disabled by default in the device tree. Enable the
node here as we have to load and boot the core in R5 SPL stage. Assign
the alias of 'remoteproc2' to the hsm node. This assigns the sequence
number '2' to HSM core which can be used during rproc_load() and
rproc_start() calls.

v4: Changelog:
1. Changed node labels from 'hsm_m4fss' to 'hsm' to match with device
   tree definition.

v3: Changelog:
1. New patch. Enable HSM nodes from DT.
