Subject: [PATCH RESEND v2 2/2] soc: ti: ti_sci_inta_msi: Enable module
 compilation support

Add module support to the TI SCI INTA MSI driver:
- Change Kconfig from bool to tristate to allow module compilation
- Add linux/module.h include for module functionality
- Add MODULE_LICENSE, MODULE_DESCRIPTION, and MODULE_AUTHOR macros

This allows the driver to be compiled as a loadable kernel module
named ti_sci_inta_msi.
