Kind value can be passed to API nvgpu_vm_map() from User
space (through IOCTL NVGPU_AS_IOCTL_MAP_BUFFER_EX)
But kind value is not checked for sane values
before storing it in bfr.kind_v
And then we use this kind value as array index
in gk20a_kind_is_supported() which is incorrect
Fix this by ensuring in nvgpu_vm_map() that the
kind value is well within range

Remove use of linux/kernel.h and linux/compiler.h. We don't use
anything in those headers.
Also replace use of linux/bitops.h with new wrapper nvgpu/bitops.h.
