[PATCH 2/3] arm: k3-binman: add tisemifalcon.bin for semi-falcon mode

This patch adds creation of tisemifalcon.bin for J784S4 EVM.

The contents are the same as the existing tispl.bin but A72's SPL and
the FDT have been removed as they are not needed in semi-falcon mode
and instead UBOOT and its FDT are added.

This reduces boot time since A72 SPL is skipped.

tispl.bin = TFA + TEE + DM + A72 SPL + FDT(A72 SPL)
tifalcon.bin = TFA + TEE + DM + UBOOT + FDT(UBOOT)
