boot/ti-k3-r5-loader: remove BR2_TARGET_TI_K3_R5_LOADER_USE_BINMAN

Since all AM62 and AM64 defconfig has been updated to use binman
and ti-k3-image-gen has been removed, binman is now mandatory
for all TI K3 SoC. So remove BR2_TARGET_TI_K3_R5_LOADER_USE_BINMAN
option since since it can't be disabled anymore.

We can remove BR2_TARGET_TI_K3_R5_LOADER_USE_BINMAN without
legacy handling since this option is not part of any Buildroot
release.

While at it, add one more like to binman dependencies in comments.
