Removes the 'priority' parameter from the IRQ_CONFIG macro.
This parameter was not used anymore in any architecture.
The priority is handled in the IRQ_CONNECT macro.
The documentation is updated as well.

When building for a certain platform, we have no idea
what architecture we are building for.
We used to specify the architecture alongside the board or platform
name and this was used to find the defconfig in arch/<arch>/configs.
By putting all board configurations we support in one place we do
not have to specify the architecture, just the configuration name.

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()
