automation/RISC-V: select APLIC and IMSIC to handle both wired interrupts and MSIs

By default, the `aia` option is set to "none" which selects the SiFive PLIC for
handling wired interrupts. However, since PLIC is now considered obsolete and
will not be supported by Xen now, APLIC and IMSIC are selected instead to manage
both wired interrupts and MSIs.
