AudioReach on the NXP i.MX8MP EVK target needs a CAPI endpoint that drives the SAI/SDMA hardware directly through the Zephyr DAI/DMA interfaces used on this platform. Add the nxp_device_sink module under fwk/platform/modules/nxp with its CAPI implementation, endpoint APIs, and build files. Wire it into the module build via a new NXP_DEVICE_SINK Kconfig option and register the nxp subdirectory in the platform modules CMake build so the module is compiled when the option is enabled.

With the nxp_device_sink module now available, enable it for the i.MX8MP EVK ADSP target so the SAI/SDMA endpoint is built and wired into the audio path. Turn on NXP_DEVICE_SINK and SHARED_INTERRUPTS in prj.conf. Enable the Zephyr DAI, DMA, SAI, SDMA, and fixed-rate clock drivers in the board conf, and mark the sai3, sdma3, mclk, and micfil device tree nodes okay in the board overlay so the hardware endpoint has the resources it needs.
