It is not possible to build only drivers/infiniband/hw/ (and ulp/)
subdirectory with command such as:
$ make ARCH=x86_64 O=./obj-x86_64/ drivers/infiniband/hw/
This fails with following error messages:
make[2]: Nothing to be done for `all'.
make[2]: Nothing to be done for `relocs'.

This patch creates a Makefile in hw/ and ulp/ and moves
each corresponding parts of drivers/infiniband/Makefile
in the new Makefiles.
It should not break build except if some hw/ drivers or ulp/
were allowed previously to be built while CONFIG_INFINIBAND
is set to 'n', but according to drivers/infiniband/Kconfig,
it's not possible. So it should be safe to apply.
