Add initial support for SoCCP on Qualcomm Kaanapali platform. SoC Control
Processor (SoCCP) is loaded by bootloader on Kaanapali. PAS loader will
check the state of the subsystem, and set the status "attached". As the
interrupts are redefined differently for Kaanapali SoCCP, list for the
interrupt properties are moved out of pas-common.
When we return fail in the rproc attach op, current remoteproc core cannot
handle it correctly for further recovery/firmware loading, which should be
generic problem shared across all remoteproc drivers that do attach and
not mandatory for normal bring up, a separate series is used for resolving
this:
