The build of driver is disabled from Linux 6.2 due to
changes in core kernel where API of_get_named_gpio_flags()
has been removed.
This APIS is removed in commit 40fc56ee608cdb ("gpiolib:
of: remove of_get_gpio[_flags]() and of_get_named_gpio_flags()")
in Linux 6.2.
Add support to use the new APIs for Linux 6.2 onwards.

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.

In Linux v5.19, the arguments to the 'suspend' function pointer defined
in the structure 'ufs_hba_variant_ops' was updated to add a 'status'
argument. Add a new test to the conftest script that checks if the
'suspend' function has a 'status' argument and use the definition
created by conftest to select which structure member is used.
This is beneficial for working with 3rd party Linux kernels that may
have back-ported upstream changes into their kernel and so the kernel
version checks do not work.

Clean-up the UFS headers by adding a new top-level header for ufshcd.h,
ufshci.h and unipro.h that will include the appropriate header
depending on kernel version. This saves replicating the kernel version
check for every source file that includes these headers.
Note that the ufshcd-pltfrm.h header is identical between v5.15, v5.16
and 6.1 kernels and so remove the duplicated versions of this header and
just use a common header for all kernel versions.

defined and if so use it. This fixes building the Tegra DRM driver

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:

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

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.
