This is being removed for a few reasons:
- AFAICT this is the only API in Zephyr that follows an allocate/free
model.
- There are no public APIs in the interrupt subsystem for releasing
or reconfiguring an interrupt. This code was relying on arch-specific
private APIs. If we really want to keep this capability we should
make these APIs public and consistent across arches.
- The use-case for this API is not clear, as Zephyr is not intended
for hot-pluggable peripherals. Built-in hardware tends to need its
interrupt for its entire life cycle.
- The current implementation of dynamic interrupts on x86 does not
support freeing a dynamic IRQ that was reserved with
irq_connect_dynamic(), causing this code not to work. To add this
would require reimplementing _get_dynamic_stub() to use a bitfield
or set of bitfields to track unused stubs rather than the simple
counter it uses now.
