rapidio: add modular build option for the subsystem core
Add a configuration option to build RapidIO subsystem core code as a
loadable kernel module. Currently this option is available only for
x86-based platforms, with the additional patch for PowerPC planned to be
provided later.
This patch replaces kernel command line parameter "riohdid=" with its
module-specific analog "rapidio.hdid=".
