dev: Add an InterruptPin class to wrap plain interrupts
Plain interrupts are currently delivered using platform-specific
interrupt controllers. This makes it hard to implement MMIO devices
with interrupts (e.g., VirtIO). This change introduces an abstract
interrupt adaptor class, InterruptPin, that can be implemented by
platforms that need to support such devices.
Devices that need to implement interrupts should take an InterruptPin
parameter. Such devices call InterruptPin::raise() to raise an
interrupt and InterruptPin::clear() to clear the interrupt.
Devices with optional interrupt capabilities may use the
IgnoreInterruptPin to ignore interrupts by default. This class can
optionally print a warning if an interrupt is triggered by setting the
'warning' parameter. WarnInterruptPin is a Python convenience class to
that warns when an interrupt is triggered.
