This patch adds a variant of ht_create_irq __ht_create_irq that takes an
aditional parameter update that is a function that is called whenever we want
to write to a drivers htirq configuration registers.
This is needed to support the ipath_iba6110 because it's registers in the
proper location are not actually conected to the hardware that controlls
interrupt delivery.

This refactoring actually optimizes the code a little by caching the value
that we think the device is programmed with instead of reading it back from
the hardware. Which simplifies the code a little and should speed things up a
bit.
This patch introduces the concept of a ht_irq_msg and modifies the
architecture read/write routines to update this code.
There is a minor consistency fix here as well as x86_64 forgot to initialize
the htirq as masked.

This moves the declarations for the architecture helpers into
include/linux/htirq.h from the generic include/linux/pci.h. Hopefully this
will make this distinction clearer.
htirq.h is included where it is needed.
The dependency on the msi code is fixed and removed.
The Makefile is tidied up.
