[PATCH 2/2] crypto: octeontx2 - Remove custom swap functions in favor of built-in sort swap

[Kuan-Wei Chiu]

The custom swap functions used in octeontx2 driver do not perform any
special operations and can be replaced with the built-in swap function
of sort. This change not only reduces code size but also improves
efficiency, especially in scenarios where CONFIG_RETPOLINE is enabled,
as it makes indirect function calls more expensive.

By using the built-in swap, we avoid these costly indirect function
calls, leading to better performance.
