feat(sgi): use new expect scripts for linux boot tests

For Neoverse reference design platforms, use the new expect scripts
to track TF-A and linux boot prints. Addtionally, update the primary
uart port to the non secure port that puts out linux logs so that the
test doesn't exit after TF-A logs are printed via secure port.
