boot/ti-k3-boot-firmware: switch to github mirror

The git.ti.com cgit server continues to be plagued with reliability
issues which are reportedly from heavy bot traffic. To combat this the
system administrators have removed the archived downloads feature from
this server.

Switch to TI's Github mirror so new downloads continue to be possible.
