Subject: [PATCH v2 2/2] irqchip: Kconfig: Added module build support for the TI interrupt aggregator

Added module build support in Kconfig for the TI SCI interrupt aggregator
driver. The driver's default build is built-in and it also depends on
ARCH_K3 as the driver uses some 64 bit ops and should only be built
for 64 bit platforms.
