modules: hal_nxp: Add core_id for RT685 HIFI4 core

1. Add core_id for RT685 HIFI4 core, this variable is
used in MCUX SDK cmake.
2. Set cmake variables 'CONFIG_MCUX_COMPONENT_driver.smartdma_mcxn'
and 'CONFIG_MCUX_COMPONENT_driver.smartdma_rt500' to "ON" as these
variables control the loading of source files in the latest driver
CMakeList.txt.
