ti-rtos-firmware: Update PATH to include ti-sci-fw

Build is failing for ti-rtos-firmware when ARAGO_BRAND = "mainline"
with below error:
"ERROR: ti-rtos-firmware-08.00.00.32-r0.0 do_fetch: Fetcher failure:
Unable to find file file://0001-Revert-soc-am64x-Makefile-Move-the-
SPL-Load-address-.patch;patchdir=../imggen anywhere."

This is because the mentioned patch is not present in the current path.
Fix this by updating the path to include ti-sci-fw
