The 128-bit multiply in pvclock.h was missing an output constraint for
EDX which caused a register corruption to appear. Thanks to Ulrich for
diagnosing the EDX corruption and Avi for providing this fix.

Commit 916f676f8d started reserving boot service code since some systems
require you to keep that code around until SetVirtualAddressMap is called.
However, in some cases those areas will overlap with reserved regions.
The proper medium-term fix is to fix the bootloader to prevent the
conflicts from occurring by moving the kernel to a better position,
but the kernel should check for this possibility, and only reserve regions
which can be reserved.

Bus specific layer must know how to return the struct device* of the device.
Implement that as a callback of iwl_bus_ops and use that callback instead of
using the priv->pdev pointer which is meant to disappear soon.
Since the struct device * is needed in hot path, iwl_bus holds a pointer to it
instead of calling get_dev all the time.

Move some PCI functionality to the new iwl_pci.[ch] files:
* the PCI_DEVICE_TABLE
* the pci_driver struct definition
* the PCI probe / remove functions
* the PCI suspend / resume functions
All these functions are now split: the trigger comes from the PCI layer which
calls to the bus generic code located in the other files.
This is the beginning only. There are still a lot of PCI related code needs
to be gathered.
