target/arm_cti: add new 'ack' and 'channel' commands 

these commands have been introduced to ease the manipulation of CTI trough
script files, these commands are:
 - $cti_name ack $event : to acknowledge a CTI event
 - $cti_name channel $channel_number $operation: to perform an operation
    on a specific channel, the possible operations are:
    gate, ungate, set, clear and pulse
