crypto: crypto4xx - move and refactor dynamic_contents helpers
This patch refactors and moves the dynamic_contents helper
functions into the crypto4xx_sa.h header file.
* get_dynamic_sa_iv_size is no longer needed, as the cryptoapi
provides the required IV size information as well.
* refactor the function declarations to use the a pointer to the
dynamic_sa_contents union, instead of the crypto4xx_ctx.
* rename get_dynamic_sa_offset_key_field to get_dynamic_sa_key_field.
It returns the pointer to the key directly.
