coresight: add jtag fuse driver

Add support for JTag Fuse driver which can be used by other
JTag save-restore driver(s) to query the state of the jtag fuses to
determine if the Hardware they manage is functionally disabled or
not.

Drivers can then take necessary actions like failing the probe if
the Hardware they manage is functionally disabled.
