This has turned in to quite a mess, and with CPUs that care using
dmaengine now it's about time to start cleaning up after the legacy DMA
code. For starters, kill off the stubs for the CPUs that don't do
anything, as well as all of the unused definitions. This leaves us with a
set of IRQs and base addresses we can deal with later.

cpu-sh4a headers take priority over cpu-sh4 ones by virtue of the build
system, there's no need to try and mingle sh4a stuff in cpu-sh4.

With the previous attempt reverted this switches to conditionalizing the
end address. Nominally VMALLOC_END, but extended for P3_ADDR_MAX in the
store queue case.

This reverts commit 20e7c297.
With store queues enabled the area above P4SEG has special properties
from the MMU's point of view, which was causing fixmap failure. We'll
have to do something else to satisfy the vmalloc range check.

In doing the evt2irq() + muxed vector conversion for various port types
it became apparent that some of the legacy port types will presently
error out due to the irq requesting logic attempting to acquire the
non-existent BRI IRQ. This adds some sanity checks to the request/free
path to ensure that non-existence of a source in itself is not an error.

This should restore functionality for legacy PORT_SCI ports.
