Subject: [PATCH] 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.

Bug 5564561
