firmware: arm_scmi: use strlcpy to ensure NULL-terminated strings

[ Upstream commit ca64b719a1e665ac7449b6a968059176af7365a8 ]

Replace all the memcpy() for copying name strings from the firmware with
strlcpy() to make sure we are bounded by the source buffer size and we
also always have NULL-terminated strings.

This is needed to avoid out of bounds accesses if the firmware returns
a non-terminated string.
