firmware: ti_sci: refactor deprecated strncpy
`strncpy` is deprecated for use on NUL-terminated destination strings [1]. We should prefer more robust and less ambiguous string interfaces. A suitable replacement is `strscpy` [2] due to the fact that it guarantees NUL-termination on the destination buffer. It does not seem like `ver->firmware_description` requires NUL-padding (which is a behavior that strncpy provides) but if it does let's opt for `strscpy_pad()`.
