[PATCH v2 3/7] arm: dts: k3-binman: Add template for packing HSM firmware

[Beleswar Padhi]

The HSM M4 core needs to be booted at R5 SPL stage so that it can be
used for further Authentication and security services. Therefore, the
firmware for the HSM core needs to be packed in tispl.bin fit image so
that it can be used by R5 SPL to boot the HSM core.

Add a template for packing the HSM firmware in tispl.bin.
