irq: Add flags to IRQ_CONNECT_STATIC() macro and irq_connect() function

Browse source 
Flags allow passing IRQ triggering option for x86 architecture.
Each platform defines flags for a particular device and then
device driver uses them when registers the interrupt handler.

The change in API means that device drivers and sample
applications need to use the new API.

IRQ triggering configuration is now handled by device drivers
by using flags passed to interrupt registering API:
IRQ_CONNECT_STATIC() or irq_connect()
