Update kernel-parameters.txt to add two new parameters:
- coresight_cpu_debug.enable is a knob to enable debugging at boot time.
- coresight_cpu_debug.idle_constraint is used to constrain idle states
to ensure Coresight CPU debug component can be accessible.

The debug APB clock is absent in hi6220 driver, so this patch is to add
support for it.

Almost low level functions from open firmware have used const to
qualify device_node structures, so add const for device_node
parameters in of_coresight related functions.

The of_get_coresight_platform_data iterates over the possible CPU nodes
to find a given cpu phandle. However it does not drop the reference
to the node pointer returned by the of_get_coresight_platform_data.
This patch also introduces another minor fix is to use
of_cpu_dev
ARMv8 architecture reference manual (ARM DDI 0487A.k) Chapter H7 "The
Sample-based Profiling Extension" has description for sampling
registers, we can utilize these registers to check program counter
value with combined CPU exception level, secure state, etc. So this is
helpful for CPU lockup bugs,
According to ARMv8 architecture reference manual (ARM DDI 0487A.k)
Chapter 'Part H: External debug', the CPU can integrate debug module
and it can support self-hosted debug and external debug. Especially
for supporting self-hosted debug, this means the program can access
the debug module from mmio
This is refactor to add function of_coresight_get_cpu(), so it's used to
retrieve CPU id for coresight component. Finally can use it as a common
function for multiple places.

Coresight includes debug module and usually the module connects with CPU
debug logic. ARMv8 architecture reference manual (ARM DDI 0487A.k) has
description for related info in "Part H: External Debug".
Chapter H7 "The Sample-based Profiling Extension" introduces several
