Determining whether the header file iosys-map.h is present in the kernel
is currently determine by kernel version. However, for Linux v5.15,
iosys-map.h has been backported in order to support simple-framebuffer
for early display. Therefore, we cannot rely on the kernel version to
indicate whether iosys-map is present. This is also true for 3rd party
Linux kernels that backport changes as well. Fix this by adding a
compile time flag, that will be set accordingly by the conftest script
if this header is present.

On SIPL stack, VI engine status memory which
is allocated by SIPL span across multiple memory
pages. IOVA calculations in KMD as per pinned
pages did not taken to account the multiple pages and
calculated IOVA based on first page base address.
This lead to VI falcon access the passed incorrect
iova address which caused Kernel OOPS at random places.
To fix this, calculate the IOVA based on adjusting
offset with respect to right page by traversing the
scatterlist. For older kernel versions(4.9) being used
in some android packages, the existing IOVA mappping is
kept as it is, as it doesn't support scatterlist.

Building the Tegra camera drivers with Linux v5.16+ kernels fail because
the driver does not use the correct kernel version for handling various
API changes in upstream. Update ther kernel version appropriately so
that the camera drivers can build with Linux v5.16+ kernels.
