Update Arm copyright notices in new math files

While working on the strstr patch I noticed several copyright headers
of the new math functions are missing closing quotes after ``AS IS.
I've added these.  Also update spellings of Arm Ltd in a few places
(but still use ARM LTD in upper case portion).  Finally add SPDX
identifiers to make everything consistent.
