88b264cfce mbedTLS SHA: Fix cloning of SHA-384 digests 
Hardware unit only reads 384 bits of state for SHA-384 LOAD,
which is enough for final digest but not enough if you plan to
resume digest in software.

c48612e516 mbedTLS SHA acceleration: Allow concurrent digest calculation, works with TLS 
SHA hardware allows each of SHA1, SHA256, SHA384&SHA512 to calculate digests
concurrently.

Currently incompatible with AES acceleration due to a hardware reset problem.

Ref TW7111.

This is not the long term solution...

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.
