The TI K3 R5 loader package essentially is a wrapper to build a special
version of U-boot SPL used as part of a multi-stage boot flow on TI K3
devices, and as such needs full flexibility as to specifying the U-Boot
sources used for the build. To accomodate this, add the same options as
already available in the regular U-Boot package. For most use cases, the
same source settings (repo URL, versions, etc.) should be used for both
ti-k3-r5-loader and uboot packages.
