[PATCH 3/4] arm: dts: k3-{j721s2/j784s4}-binman: Pack HSM firmware inside tispl.bin

Pack the HSM firmware in tispl.bin fit image so that it can be unloaded
and used by R5 SPL to boot the HSM core. By default, point to the
firmware for HS-SE device type. This needs to be changed to point to
appropriate firmware when using a different device type.
