mc-utils driver support is needed on T264, and it should be present in
nvidia-t264 repo, so as to avoid leaking any information. Also, we need
to make sure once T264 is public the existing mc-utils driver can be
updated easily for T264 support.
Hence first copy the existing mc-utils driver from nvidia-oot into
nvidia-t264, then make changes for T264 and finally when T264 is public,
just cherry-pick the addional changes in nvidia-oot and clean up driver
from nvidia-t264. This change is doing the first step i.e. copying
existing mc-utils driver code from nvidia-oot into nvidia-t264.

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)

- Add numa_node_id property in nvmap_heap and nvmap platform carveout
structures to hold numa id info i.e. numa node on which this heap is
created.
- gpu0 and gpu1 would have same heap bit but different numa node ids.
- Update buffer allocation function: If user specify the allocate from
a particular numa node instance of the heap, then allocate from that
particular instance. By default input to numa node id is NUMA_NO_NODE,
so in this case, iterate over heaps on all numa nodes to satisfy the
allocation request e.g. if user specify to allocate from gpu carveout
without specifying any particular numa node, then iterate over all gpu
carveouts on all numa nodes, whichever has sufficient free memory,
allocate from thatheap instance.
- Update debugfs functions to pass heap type and numa id, so that
debugfs info is fetched from correct heap instance.

In Linux v6.2, the Tegra IVC driver was updated to support iosys-map and
this breaks building some of the out-of-tree drivers for Linux v6.2+
kernels. In Linux v6.3, the GPIO OF APIs were removed and this breaks
building some of the out-of-tree drivers that use these legacy APIs. For
now the broken drivers are not built for these corresponding kernels.
Instead of checking the kernel version in the Makefile for the
corresponding broken driver, move the kernel version checking to the
top-level Makefile and add CONFIG definitions that can be used the
various Makefiles.
This is also needed for working with 3rd party Linux kernels that may
have upstream backports and need to set these CONFIG variables for their
