The PCI hotplug eject register has always returned 0, so let's redefine
it as a hotplug feature register. The existing model of using separate
up & down read-only registers and an eject via write to this register
becomes the base implementation. As we make use of new interfaces we'll
set bits here to allow the BIOS and AML implementation to optimize for
the platform implementation.
