Subject: [PATCH v4 2/2] irqchip/ti-sci-inta : Add module build support

From: Nicolas Frayer <nfrayer@...libre.com>

Add 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.

Add MODULE_LICENSE which is mandatory to support module build.
