Instead of using kernel version checks in the Tegra DRM driver for the
tegra_fb_ops structure, just check if the appropriate definition is
defined and if so use it. This fixes building the Tegra DRM driver
against some 3rd party kernels that include backports from upstream.
Note that this also aligns the driver closer to the upstream code by
using the same definitions that the upstream driver uses.

CONFIG_HAVE_ARCH_PFN_VALID has been removed by following upstream patch:
https://lkml.kernel.org/linux-mm/20210527174913.GJ8661@arm.com/T/
Hence kernel k5.15 onwards uses pfn_valid definition from mmzone.h,
while k5.10 uses pfn_valid definition from init.c
pfn_valid definition for k5.10 has last call to memblock_is_map_memory
which is missing in current definition of pfn_valid. Hence bad pte fault
is seen for carveout buffers. Use pfn_is_map_memory instead of pfn_valid
as it ultimately calls memblock_is_map_memory.

When a buffer is allocated using NvRmMemHandleAllocAttr, the refcount
will be as followed
- Handle's ref count: 2
- Ref's dup count: 1
- Dmabuf's ref count: 1
When this buffer is freed, which calls nvmap_free_handle_from_fd and
then it calls nvmap_free_handle. In nvmap_free_handle, we decrement
ref's dup count, so the ref's dup count become 0. As dup count is 0,
we decrement dmabuf's ref count as well, so dmabuf's refcount become 0,
which would call nvmap_dmabuf_release, which would set dmabuf to NULL.
But that action is not immediate sometimes, hence we can lead to null
pointer dereference. dmabuf is set to NULL in dmabuf release by taking
handle's lock, so use the same one while reading dmabuf's refcount.

The Nvhost-related APIs have been deprecated and are no longer
supported since our migration from K510 to K515. Therefore, the camera
platform driver should refrain from using "nvhost_*" functions to set
the clock rate.
Integrate the common operation callback interface into the
tegra_camera_dev_info structure. This modification allows individual
drivers to achieve clock set rate operations by registering the
callback and completing the implementation.

This change adds a cooling device driver to notify the user space of the
thermal trip event. To avoid having user space process poll the
cooling state, a sysfs node is exposed that supports blocking reads.
The driver also supports a timeout (in milliseconds) for blocking reads
which can be done by writing the value to thermal_trip_event_block node
before reading. The blocked user space process will be woken up when the
cooling device becomes active or times out.
