Anas Nashif 6bca3724c1 drivers: set default priority for drivers
Use a default priority to avoid Kconfig blocking when priority
is not set in SoC or Board.

Dmitriy Korovkin 57f2741e4f init: Implement fine-grained initialization policy
Put initialization priorities as device driver Kconfig
parameter.

Initialization priority value for each platform is defined
in the platform Kconfig file.

Drivers and platform code use SYS_DEFINE_DEVICE to add
and initialization function.

Peter Mitsis f1a4760157 Fix Kconfig SHARED_IRQ_1_PRI dependency
The kernel configuration option SHARED_IRQ_1_PRI is dependent upon
SHARED_IRQ_1, not SHARED_IRQ_0.

Peter Mitsis 5084b6da56 Fix various default IRQ priorities
Changes the default IRQ priority level from 0 to 2 for the following
kernel configuration options as priorities 0 and 1 are reserved for the
first 32 IDT entries.

	SHARED_IRQ_0_PRI
	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

Daniel Leung 006555a17b shared_irq: add config options for interrupt triggers
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.

Dirk Brandewie 002c53b225 drivers: add shared interrupt driver
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.
