firmware: ti_sci: Add support for getting resource with subtype

Browse source 
With SYSFW ABI 3.0 changes, interrupts coming out of an interrupt
controller is identified by a type and it is consistent across SoCs.
Similarly global events for Interrupt aggregator. So add an API to get
resource range using a resource type.
