Aaron Durbin 8d4f36f436 UPSTREAM: soc/intel/apollolake: add initial ITSS support
The interrupt and timer subsystem (ITSS) sits between the APIC
and the other logic blocks. It only supports positive polarity
events, but there's a polarity inversion setting for each IRQ such
that it can pass the signal on to the APIC according to the
expected APIC redirection entry values. This support is needed
in order for the platform/board to set the expected interrupt
polarity into the APIC for gpio signals.
