coresight-cti: Increase the number of CTI triggers

On some of the CTI devices the number of input and output
triggers available on the HW have increased. We are increasing
the number of maximum possible CTI triggers in order to accommodate
these devices. For CTI devices with less than the max number of
available triggers, the extra triggers will be treated as
write ignore and read zero.
