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.

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.

For example, the GPIO and I2C controllers are under same interrupt line through PCI bus. The triggering condition is level, active-low.
