coresight: cti: Access ASICCTL only when implemented
According to the Arm ARM (DDI 0487 L.b), ASICCTL is implemented only
when CTIDEVID.EXTMUXNUM is non-zero.
Based on CTIDEVID.EXTMUXNUM, add a flag 'asicctl_impl' to indicate
whether the register is implemented, and access ASICCTL conditionally
based on the flag.
Allow the sysfs node to be visible only when the register is
implemented.
