Add helper function msi_desc_to_pci_sysdata() to retrieve sysdata from
an MSI descriptor. To avoid pulling include/linux/pci.h into
include/linux/msi.h, msi_desc_to_pci_sysdata() is implemented as a normal
function instead of an inline function.

As it turns out the current IRQ number will *always* be available from
SIR register which renders the reads of PENDING registers as plain
unnecessary overhead.

In order to catch any situation where SIR reads as zero, we're adding
a WARN() to turn it into a very verbose error and users actually
report it.

With this patch average running time of omap_intc_handle_irq() reduced
from about 28.5us to 19.8us as measured by the kernel function
profiler.

Tested with BeagleBoneBlack Rev A5C.
