IB: Allow build of hw/ and ulp/ subdirectories independently
It is not possible to build only the drivers/infiniband/hw/ (or 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.
