Currently, the kind map initialization inherits from earlier
chips' kind map definitions and simply adds on newly supported
features. This is dangerous as changes in older architectures
may affect newer architectures in unpredictable ways.
This patch removes inheritance between subsequent architectures'
kind map initializations.

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.
