Fix include paths for in-tree builds

Some source files include header files using <> even though the header
file is not in a directory typically in the system include path. This
works when compiling the kernel with an O= option (which stores built
files outside the source tree) because the kernel adds various extra
source paths to the system include path. However, this doesn't happen when
building in-tree, so the source must be fixed to use "" for "local" files.

Similarly, fix one usage of "" where no path was specified in the ""
filename, whereas the header was in a relative directory to the source.
Again, with O= I believe this works because the kernel added the file's
location into the include path, but doesn't for in-tree builds.

Note: Parts of the original commit apply to source that has been moved
to linux-nvidia.git; see change Icf4f94b671e73c0a889bb996edc3f15d5fbde98b
for that part of the original rel-28 change.
