[PATCH] htirq: allow buggy drivers of buggy hardware to write the registers
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.
