driver: ssp: Refactor SSP driver to use SSP_IP_VER for version checks

This commit updates the SSP driver to use the newly defined
SSP_IP_VER macros for IP version checks instead of relying
on CONFIG_SOC_* macros. The change ensures better readability
and maintainability by centralizing the IP version definitions
and comparisons.
