build,Makefile: add default Vivado SDK path to build

And parametrize the Vivado release version. Usually, the usecase is to use the default /opt/Xilinx path. This change also passes the Vivado SDK path (for the compiler) to buildroot so that it builds. Signed-off-by: Alexandru Ardelean <[email protected]>
