With this patch the python ArmInterruptPin SimObject matches to the
C++ ArmInterruptPinGen. The latter is in charge of generating
the ArmInterruptPin (which is not a SimObject anymore).
This is meant to ease the generation of ArmInterruptPins: by
not being SimObjects we are not forced to instantiate them
in the configuration script; we can generate them dynamically
instead throughout simulation.

Add GIC-based interrupt adaptor implementations that support PPI
(ArmPPI) and SPI (ArmSPI) delivery. In addition to being useful for
"normal" memory-mapped devices, the PPI adaptor makes it possible to
use the same device model to generate both PPIs and SPIs (e.g., the
PMU).

Move the (common) GIC initialization code that notifies the platform
code of the new GIC to the base class (BaseGic) instead of the Pl390
implementation.

|
This patch moves the GIC interface to a separate base class and makes
all interrupt devices use that base class instead of a pointer to the
PL390 implementation. This allows us to have multiple GIC
implementations. Future implementations will allow in-kernel GIC
implementations when using hardware virtualization.
