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()

The kernel configuration option SHARED_IRQ_1_PRI is dependent upon
SHARED_IRQ_1, not SHARED_IRQ_0.

SHARED_IRQ_1_PRI
I2C_DW_0_INT_PRIORITY
GPIO_DW_0_PRI
GPIO_DW_1_PRI
SPI_INTEL_PORT_0_PRI
SPI_INTEL_PORT_1_PRI

In order to have drivers that are usable cross architecture the
signature for IRQ_CONFIG needs to be the same to avoid #ifdef hell in
the driver code based on architecture.
Update the macro and it usage for existing drivers

Gets rid of the trailing initialization level character from the
name of the device variable generated by the macro, since it serves
no useful purpose. (The linker scripts place the various initialization
sections in ascending order based on the name of the section, so there
is no need to embed the initialization level in the variable name itself.)

This adds options to the shared IRQ driver so the interrupt
triggering condition can be specified.
For example, the GPIO and I2C controllers are under same
interrupt line through PCI bus. The triggering condition
is level, active-low. So this option can be used by
the Galileo platform to program the IO-APIC correctly.

This driver allows multiple drivers to share a common interrupt
line. This functionality is required on system that conform to the PC
interrupt structure. In the context of Zephyr this is needed for
SOC's that have their I/O IP blocks behind a PCI interface. Due to the
limited number of interrupt lines provided by the PCI interface
multiple IP blocks may be configured to share an interrupt line.
Drivers that share interrupts must be modified to *not* register their
own interrupt service routine as part of their configuration/initialization
but instead bind to the correct instance of this driver by name, then
register their interrupt service routine with this driver.
