soc: xtensa: nxp_adsp: Enable cache management API for NXP SoCs

Thanks to PR [1] which introduces support for cache management
operations on xtensa architecture NXP SoCs can now use the
Zephyr native cache management API.

This commit enables some configurations that will allow us
to use the native Zephyr cache management API.
