[uU PATCH 5/8] binman: sysfw: Add support for packaging tiboot3.bin and sysfw.itb

[Neha Malcom Francis]

For devices that require sysfw.itb, board config binary artifacts must
be populated in the R5 output directory. These can be used by binman to
package sysfw.itb.

config.mk for mach-k3 updated to generate the required binaries using
tibcfg_gen.py.

K3_CERT_GEN has been introduced in config.mk to remove hardcoding of the
certificate signing script.
