f the interrupt router registers can only be done by
a system co-processor and the driver needs to send a message to this
co processor over TISCI protocol.

apis doing the same. Use the default parent apis instead of writing

Each resource with in the device can be uniquely identified as defined
by TISCI. Since this is generic across the devices, resource allocation
also can be made generic instead of each client driver handling the
resource. So add helper apis to manage the resource.

Introduce irq_chip_{request,release}_resource_parent() apis so
that these can be used in hierarchical irqchips.

TISCI abstracts the handling of IRQ routes where interrupt sources
are not directly connected to host interrupt controller. Add support
for the set of TISCI commands for requesting and releasing IRQs.
