modules: hal_nxp: mcux-sdk-ng: Fix RT595 F1 build error

In MCUX SDK NG, the `core_id` and `core_id_suffix_name` are
different concepts, generally the values are the same. But
there are exeptions, such as RT595 F1.

Zephyr's `CONFIG_MCUX_CORE_SUFFIX` is actually MCUX SDK's
`core_id_suffix_name`. SDK NG CMake needs `core_id`, but
current integration layer uses `CONFIG_MCUX_CORE_SUFFIX`
as `core_id`, so there is build error with RT595 F1.

Fix the code that convert `CONFIG_MCUX_CORE_SUFFIX` to `core_id`,
handle the special case.
