Currently ARM and MIPS both have nearly identical copies of the APM
emulation code in their arch code. Add yet another copy of it to
drivers char and make it selectable through SYS_SUPPORTS_APM_EMULATION.

This reverts commit 2943ecf2ed32632473c06f1975db47a7aa98c10f.
This should go through the SPI maintainer, it was my fault that it did
not. Especially as it conflicts with other patches he has pending.

The arch hooks arch_setup_msi_irq and arch_teardown_msi_irq are now
responsible for allocating and freeing the linux irq in addition to
setting up the the linux irq to work with the interrupt.
arch_setup_msi_irq now takes a pci_device and a msi_desc and returns
an irq.
With this change in place this code should be useable by all platforms
except those that won't let the OS touch the hardware like ppc RTAS.

We need to be able to get from an irq number to a struct msi_desc.
The msi_desc array in msi.c had several short comings the big one was
that it could not be used outside of msi.c. Using irq_data in struct
irq_desc almost worked except on some architectures irq_data needs to
be used for something else.
So this patch adds a msi_desc pointer to irq_desc, adds the appropriate
wrappers and changes all of the msi code to use them.
The dynamic_irq_init/cleanup code was tweaked to ensure the new
field is left in a well defined state.

Since msi_remove_pci_irq_vectors is designed to be called during
hotplug remove it is actively wrong to query the hardware and expect
meaningful results back.
To that end remove the pci_find_capability calls. Testing
dev->msi_enabled and dev->msix_enabled gives us all of the information
we need.

With the removal of msi_lookup_irq all of the functions using msi_lock
operated on a single device and none of them could reasonably be
called on that device at the same time.
Since what little synchronization that needs to happen needs to happen
outside of the msi functions, msi_lock could never be contended and as
such is useless and just complicates the code.

The function msi_lookup_irq was horrible. As a side effect of running
it changed dev->irq, and then the callers would need to change it
back. In addition it does a global scan through all of the irqs,
which seems to be the sole justification of the msi_lock.
To remove the neede for msi_lookup_irq I added first_msi_irq to struct
pci_dev. Then depending on the context I replaced msi_lookup_irq with
dev->first_msi_irq, dev->msi_enabled, or dev->msix_enabled.
msi_enabled and msix_enabled were already present in pci_dev for other
reasons.

The PCI save/restore code doesn't need to care about MSI vs MSI-X, all
it really wants is to say "save/restore all MSI(-X) info for this device".
This is borne out in the code, we call the MSI and MSI-X save routines
side by side, and similarly with the restore routines.
So combine the MSI/MSI-X routines into pci_save_msi_state() and
pci_restore_msi_state(). It is up to those routines to decide what state
needs to be saved.

I don't see any reason why we need pci_msi_quirk, quirk code can just
call pci_no_msi() instead.
Remove the check of pci_msi_quirk in msi_init(). This is safe as all
calls to msi_init() are protected by calls to pci_msi_supported(),
which checks pci_msi_enable, which is disabled by pci_no_msi().
The pci_disable_msi routines didn't check pci_msi_quirk, only
pci_msi_enable, but as far as I can see that was a bug not a feature.

There's an existing quirk for the kernel to use 1k IO space granularity
on the Intel P64H2. It turns out however that pci_setup_bridge() in
drivers/pci/setup-bus.c reads in the IO base and limit address register
masks it off to the nearest 4k, and writes it back. This causes the
kernel to be on 1k boundaries and the hardware to be 4k aligned. The
patch below fixes the problem.
