As part of profiler show operation triggered through sysfs,
profiler data is only seen in the kernel log.
Add a change to copy the profiler contents in the profiler
buffer as well so that the buffer content is visible at the
place where sysfs read is issued.
Note that there is a limitation in buffer size used in sysfs
read and write operations, which is equal to PAGE_SIZE.
And so, checks are added to detect buffer overflow while
writing profiler data in the buffer.

1. tegra_bl_debug_probe checks if either bl_prof_dataptr, bl_prof_ro_ptr
or bl_debug_data are not passed by kernel command line parameter.
Post this check, it retrieves bl_prof_dataptr and bl_prof_ro_ptr
data from DT and does not retrieve anything for bl_debug_data.
There is no need for checking bl_debug_data as it is not being
queried from DT in the probe function. Hence, remove the check for
bl_debug_data from probe.
2. Add prints in probe function to print bl_prof_dataptr and bl_prof_ro_ptr.

ADSP host driver is enhanced to be multi-instance
capable and reentrant:
- Trailing unique identifier string in compatible DT property, like
"adsp", "adsp1" or "aon", is used to identify the driver instances
- Each probed driver instance is inserted into a global list, from
which the handle can be fetched using 'nvadsp_get_handle' API
(passing the above unique identifier as argument)
- Above unique identifier is also used as name for the DBFS
directory (containing files like adsp_console, adsp_logger, etc.)
- 'nvadsp_get_handle' is the only exported API; all other APIs are
accessible via function pointers within 'struct nvadsp_handle'
- APIs above maintain one-is-to-one correspondence with all
legacy APIs, with the addition of a new argument
'struct nvadsp_handle *' at the beginning
- Legacy APIs continue to be supported, but they are hardwired to
work only if the kernel probes just one driver instance
- All driver files are cleaned up to not use any global state
variables (necessary for reentrancy)

boot, this should get called very early in the resume sequence.
2. Register PM notifier to know when resume is complete. This helps
in profiling the time when entire resume sequence is complete.
These 2 timestamps should approximately indicate the time it takes

Probing a driver can be deferred if a resource is not ready and this is
accomplished by returning -EPROBE_DEFER from the .probe function. This
tells to kernel to probe the driver again some time later. When probing
a driver is deferred it is not necessary to print an error message
because this is an expected error case. To avoid printing an error
message on probe deferral, the dev_err_probe() function can be used
which will only print an error if the error code is not -EPROBE_DEFER.
Therefore, update the camera drivers to use dev_err_probe() to avoid
printing an error message when -EPROBE_DEFER if returned from ICC.
This change will also cause the probing of the rtcpu-debug driver to
be deferred if -EPROBE_DEFER is returned and prevent the rtcpu-debug
driver from being probed at all if an real error is encountered.

The compiler option -Wmissing-prototypes is being enabled globally in
the upstream Linux kernel and this causes build failures for various
drivers. The build failures occur because either the driver is missing
an include file which has the prototype or because the function is not
declared statically when it should be (ie. there are no external users).
Fix the various build failures and enable -Wmissing-prototypes to
prevent any new instances from occurring. Note that the only driver that
is not fixed at the moment is rtl8822ce due to large number of failures
and so build this with '-Wno-missing-prototypes' for now, which is not
different to how it was being compiled prior to this change.
