In Linux v6.13, commit 7bac65687510 ("scsi: ufs: qcom: Power off the PHY
if it was already powered on in ufs_qcom_power_up_sequence()") removed
the 'reinit_notify' function pointer from the 'ufs_hba_variant_ops'
structure. This breaks the build for the Tegra UFS driver because we
maintain a copy of the upstream header file 'ufshcd-priv.h' in order to
build the Tegra UFS driver as an out-of-tree driver.
It is possible to fix this by using conftest to detect if the
'reinit_notify' function pointer is defined in the kernel's
'ufs_hba_variant_ops' structure. However, given that the Tegra UFS
driver does not use the 'ufshcd_vops_reinit_notify' where this
function pointer is referenced, it is simpler to remove the function
ufshcd_vops_reinit_notify completely.

Some distros might use old kernel source but with some latest upstream
kernel patches backported to their kernel source tree. To deal with this
scenario and avoid kernel compilation failure, use conftest to check the
existence of features against the kernel source tree which the OOT
modules are built upon and do the conditional build based on the test
result generated with the conftest tool.
Use NV_DEVFREQ_HAS_FREQ_TABLE to determine whether freq_table field is
there in struct devfreq data strcuture, and choose the correct path for
building the module.
Use tegra_wmark-specific devfreq_get_freq_range always to avoid kernel
version check and conftest check. Since devfreq_get_freq_range exists in
the devfreq-specific governor.h (e.g. drivers/devfreq/governor.h) file
instead of globabl linux kernel include header files
(e.g. include/linux/devfreq.h), conftest cannot be used to the existence
of devfreq_get_freq_range kernel function.

Remove the legacy downstream quirk 'UFSHCD_QUIRK_ENABLE_STREAM_ID' and
always use the supported upstream quirk from now on. The legacy quirk
will never be upstreamed and so to support 3rd Party Linux distributions
that will not have this quirk, we should only support the official
upstream quirk.

The UFS headers are moved to include as public headers from
Linux 5.19. Use the headers directly from the core kernel
instead of making the copy in drivers-private for nvidia-oot.
Keep copy of only those drivers which are still in the
drivers folder in core kernel.
This will help to align all definition which driver needs to
sync with core driver available in the core kernel.

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.
