Current name of coresight component's folder consists of prefix of
the device and the id in the device list. When run 'ls' command,
we can get the register address of the device. Take CTI for example,
if we want to set the config for modem CTI, but we can't know which
CTI is modem CTI from all current information.
cti_sys0 -> ../../../devices/platform/soc@0/138f0000.cti/cti_sys0
cti_sys1 -> ../../../devices/platform/soc@0/13900000.cti/cti_sys1
Add label to show hardware context information of each coresight
device. There will be a sysfs node label in each device folder.
cat /sys/bus/coresight/devices/cti_sys0/label

Coresight components may be in a power domain which is the case for the Arm
Juno board. Allow a single 'power-domains' entry for Coresight components.

Each CoreSight component has slightly different requirements and
nothing applies to every component, so each CoreSight component has its
own schema document.
