Add KMS only build flag
Rather than refactoring all our init code only to have it go away when
we remove UMS, this patch adds a build time flag to allow the driver to
assume KMS support.
With this flag active, the driver will not request that I/O or MEM be
enabled at probe time, which can allow the server (if other drivers also
cooperate) to run as a non-root user.
