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.

Guest VM has access to all of the profiler carveout right now so that
it can read full carveout and dump all the entries.
Right now address and size of Guest VM owned profiler carveout is parsed
from kernel command line. And the address of full profiler carveout
(containing logs of other VMs too) is calculated based on assumptions.
Current architecture is now getting reworked so that only a privileged
Guest VM can access full carveout and that too in read-only mode. Each
VM will have read-write access to its own carveout to read/write
profiler entries of that VM.
Update tegra_bootloader_debug_init.c to parse tegra_bl_prof_ro_start and
tegra_bl_prof_ro_size from kernel command line. These values indicate
address and size of the full read only carveout.
In tegra_bootloader_debuginit(), map the address of read only carveout
to tegra_bl_mapped_prof_ro_start and set is_privileged_vm to true.
Only privileged VM will be assigned this read only address by BL.
tegra_bl_mapped_prof_start continues to map to read-write carveout
owned by the VM.
Update profiler_show() so that it reads entries from the read-only
carveout if is_privileged_vm is set, otherwise it reads from read
write carveout.
