0647d1e922 esp32 hwcrypto: Rework hardware crypto locking 
Should protect against concurrent use of hardware crypto primitives,
with good performance.

Not necessary to call esp_aes_acquire_hardware(),
esp_sha_acquire_hardware(), etc when using these APIs. These are
provided for external users calling the hardware crypto hardware
directly, to coexist with this implementation.
