[PATCH v4 0/2] coresight: core: Add device name support

[Mao Jinlong]

With current design, the name of the non-cpu bounded coresight
component is the device type with the number. And with 'ls' command
we can get the register address of the component. But from these
information, we can't know what the HW or system the component belongs
to. Add device-name in DT to support it.

cti_sys0 -> ../../../devices/platform/soc at 0/138f0000.cti/cti_sys0
cti_sys1 -> ../../../devices/platform/soc at 0/13900000.cti/cti_sys1
tpdm0 -> ../../../devices/platform/soc at 0/10b0d000.tpdm/tpdm0
tpdm1 -> ../../../devices/platform/soc at 0/10c28000.tpdm/tpdm1
tpdm2 -> ../../../devices/platform/soc at 0/10c29000.tpdm/tpdm2

Change since V3:
1. Change device-name to arm,cs-dev-name.
2. Add arm,cs-dev-name to only CTI and sources' dt-binding.

Change since V2:
1. Fix the error in coresight core.
drivers/hwtracing/coresight/coresight-core.c:1775:7: error: assigning to 'char *' from 'const char *' discards qualifiers

2. Fix the warning when run dtbinding check.
Documentation/devicetree/bindings/arm/arm,coresight-cpu-debug.yaml: device-name: missing type definition

Change since V1:
1. Change coresight-name to device name.
2. Add the device-name in coresight dt bindings.
