coresight-etm3x: Change the name of the ctxid_val to ctxid_pid
'ctxid_val' array was used to store the value of ETM context ID comparator which actually stores the process ID to be traced, so using 'ctxid_pid' as its name instead make it easier to understand. This patch also changes the ABI, it is normally not allowed, but fortunately it is a testing ABI and very new for now. Nevertheless, if you don't think it should be changed, we could always add an alias for userspace.
