5f19f14fed sh: intc: Kill off special reservation interface.
At present reserving the IRLs in the IRQ bitmap in addition to the
dropping of the legacy IRQ pre-allocation prevent IRL IRQs from being
allocated for the x3proto board.

The only reason to permit reservations was to lock down possible hardware
vectors prior to dynamic IRQ scanning, but this doesn't matter much given
that the hardware controller configuration is sorted before we get around
to doing any dynamic IRQ allocation anyways. Beyond that, all of the
tables are __init annotated, so quite a bit more work would need to be
done to support reconfiguring things like IRL controllers on the fly,
much more than would ever make it worth the hassle.

c30b9c432e sh: Enable PIO API for hp6xx and se770x.
Both of these boards are still using the PIO API sans PCI, and will need
to be carefully converted. As conversion is out of scope for this merge
window, simply make sure NO_IOPORT doesn't get accidentally set for
these, joining a long list of other crap platforms.

63dc02bde6 sh: Kill off machvec IRQ hinting.
Everything is using sparseirq these days, so we have no need to
arbitrarily size nr_irqs ahead of time. The legacy IRQ pre-allocation
likewise has no meaning for us, so that's killed off too. We now depend
on nr_irqs expansion by the generic hardirq layer instead.

It's also worth noting that the majority of boards had completely bogus
values for their nr_irqs relative to their CPU and configurations, so
this ends up correcting behaviour for quite a few platforms.

7f47c7189b sh: dma: More legacy cpu dma chainsawing.
Attempt to "tidy" up some of the multi IRQ handling and base + IRQ
management. This should keep it limping along without too much hassle,
and no new parts should ever be enabling or using this API anyways.

It doesn't get any closer to lipstick on a pig as this.

e24cca19ba sh: Kill off MAX_DMA_ADDRESS leftovers.
We don't support the ISA DMA API, so this is only ever misused. The
dma-sh case inadvertently broke the dreamcast case by testing the wrong
variable for the total number of channels, so this fixes that up too.

2ff9f317f1 sh: Tidy up some of the cpu legacy dma header mess.
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.

c3e0af9879 Revert "sh: Ensure fixmap and store queue space can co-exist."
This reverts commit 20e7c297ef.
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.
