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
Linux kernel.

Consider the following execution scenario, it can lead to a data race
Thread 1 Thread 2
-------------------------------------------------------
NvRmMemHandleAllocAttr
NvRmMemGetFd
NvRmMemHandleFromFd close(fd), NvRmMemHandleFree
When thread 1 is executing NvRmMemHandleFromFd while thread 2 is closing
the fd and freeing the handle, then following sequence will lead to
accessing a freed dma-buf and may lead to dereference issue.
- TH1: Get handle from fd and increment handle's refcount.
- TH2: Close the fd and start execution of NvRmMemHandleFree.
- TH2: Decrement ref's dup count, it will become 0, hence ref would be
freed and dma-buf as well, but as handle's refcount is incremented in
step 1, handle won't be freed.
- TH1: Resume HandleFromFd part, call to nvmap_duplicate_handle. Ref is
already freed, so generate new ref and increment dma-buf's count but as
dma-buf is freed already, accessing dma-buf will lead to dereferene
issue. Hence, we need to add a null check here and return error value in
such scenario.
Also, add check for return value of nvmap_handle_get, at missing places.
