The use of ramstage.a required the build system to handle some
object files in a special way, which were put in the drivers
class.
These object files didn't provide any symbols that were used
directly (but only via linker magic), and so the linker never
considered them for inclusion.
With ramstage.a gone, we can drop this special class, too.

ramstage.a has two issues:
1. duplicate source filenames don't survive the ar(1)
treatment properly (so files aren't considered)
2. ld doesn't resolve symbols if it isn't forced to, in
particular no overrides of weak symbols
Downside: The resulting binaries get slightly larger.
Link time optimizations should fix that, as would tighter
rules in the build system (to not compile unused code in
the first place).

is that POST codes should be written to an IO port (e.g. LPC) if POST

This enables POST codes by default using "default y" to avoid

when they get written back. This resulted in leaking TDs with an invalid
reference to a freed interrupt queue.
The new approach: Mark the interrupt queue to be destroyed and handle
the freeing later, when the controller posted the last TD to the done
queue.

The linking of interrupt queues into UHCI controller's framelist (in
uhci_create_intr_queue()) was incomplete. The implementation of
uhci_destroy_intr_queue() was even worse, looking like it wanted to
clean up more than uhci_create_intr_queue() did.
This patch follows the simple approach that we used for OHCI and EHCI:
Each slot in the framelist holds only one interrupt queue. Therefore, we
have to look for free slots each time we want to link an interrupt queue
into the framelist. In return, we have a much simpler structured
framelist.
With this, USB devices using interrupt transfers (e.g. keyboards) can be
detached cleanly from UHCI controllers. Also, more than one of such
devices can be attached without further risk.
