This includes interrupt number and a tweak used when probing the driver
(which must match hardware configuration).

/* Interrupts must be set up interestingly -- shift them all by 32 like
* on the other platforms.
*
* We want interrupt 103 + 32. To properly get it from IRQ_STEER we have
* to divide this by 64 (gives result 2 and remainder 7) due to how the
* IRQ_STEER driver interacts with SOF.
