005042f3eb crypto: tegra: Update crypto_engine_ctx handling 
In Linux v6.6, the crypto_engine_ctx structure was removed and the
crypto_engine_ops was moved from this structure to the crypto_alg
structure. The Tegra Security Engine driver was updated accordingly to
populate the crypto_engine_ops in the appropriate structure depending
on whether the crypto_engine_ctx structure is present or not.

Currently conftest is using the presence of the crypto_engine_ctx
structure to decide where to populate the crypto_engine_ops. While
this works, it is possible that a kernel older than v6.6 also includes
a backport of commit e5e7eb023f24 ("crypto: engine - Move
crypto_engine_ops from request into crypto_alg") that moves the ops
to the crypto_alg structure. Although backporting this commit alone
should not cause any problems, it is better to detect if this commit
is present rather than relying on the presence of crypto_engine_ctx
structure.

To detect the presence of commit e5e7eb023f24 we can simply detect if
one of the functions added and exported by this commit is present.
For example, the function crypto_engine_register_aead() was added and
exported by this commit. Therefore, update conftest to detect if
commit e5e7eb023f24 is present and then update the Tegra Security
Engine accordingly.

It may happen that the variable req->iv may have stale values or
zero sized buffer by default and may end up getting used during
encryption/decryption. This in turn may corrupt the results or break
the operation. Ensure not use IV for algorithms like AES ECB where IV
is not expected.

fc72250a45 crypto: tegra: Reserve keyslots to allocate dynamically 
The HW supports only storing 15 keys at a time. This limits the number
of tfms that can work without failutes. Reserve keyslots to solve this
and use the reserved ones during the encryption/decryption operation.
This allow users to have the capability of hardware protected keys
and faster operations if there are limited number of tfms while not
halting the operation if there are more tfms.

e09a390449 crypto: tegra: Fix HASH intermediate result handling 
The intermediate hash values generated during an update task were
handled incorrectly in the driver. The values have a defined format for
each algorithm. Copying and pasting from the HASH_RESULT register
balantly would not work for all the supported algorithms. This incorrect
handling causes failures when there is a context switch between multiple
operations.

To handle the expected format correctly, add a separate buffer for
storing the intermediate results for each request. Remove the previous
copy/paste functions which read/wrote to the registers directly. Instead
configure the hardware to get the intermediate result copied to the
buffer and use host1x path to restore the intermediate hash results.
