Use "request_resource()" to properly fix up PCI resource clashes.
This is made possible by the previous resource allocation ordering
patch.
Now that we run the pre-existing PCI resource discovery _before_
ACPI resources have been added, we should not "insert" the resources
into any existing tree. If they clash with existing resources, we
should re-allocate them (later, when we have the full resource map).

[PATCH] PCI resource allocation re-ordering
This re-orders the PCI and ACPI IO resource assignment as suggested by
Linus.
With this patch, now the sequence of reserving resources is:
1. PCI claim BAR
2. ACPI reserve motherboard resources
3. PNP reserve motherboard resources
4. PCI allocate resources for uninitialized PCI devices
This way the kernel allocates new PCI resources after it has full
knowledge of the resource state, and at the same time allows ACPI and
PnP to be run _after_ we've filled in our knowledge about pre-allocated
resources.
The way it is done is to make the last phase of the original PCI assign
resources code to be an 'fs_initcall', along with the ACPI and PnP
initializations.
The blacklist stuff is broken. When set_using_dma() calls into
->ide_dma_check(), it returns __ide_dma_off() for a blacklisted drive.
This of course succeeds, returning success to the caller of ->ide_dma_check().
Not so good... It then uncondtionally calls ->ide_dma_on(), which turns on
DMA for the drive.
This moves the check to __ide_dma_on() so we also catch the buggy
->ide_dma_check() defined by various chipset drivers.
