* @brief SHA256 multi-buffer one-shot hashing.

* Notes:
* - Currently only supports num == 2.
* - This API is intended for internal acceleration paths.
* - Callers must ensure all parameters are valid (data, digest arrays and their elements
* must not be NULL; outlen must point to a valid uint32_t; *outlen >= 32 bytes).
* - Currently only supports num == 2 on AArch64 with SHA2-ASM.
* - nbytes is the same length for all lanes in this one-shot API.
*
* @param data [IN] Input pointer array. data[i] is message pointer for lane i.
