Bence Szépkúti d4585ff3c5 Fix removal of deprecated PSA constants 
Due to a misplaced #endif, the (non-functional) macro definitions were
not properly removed from crypto_compat.h if MBEDTLS_DEPRECATED_REMOVED
was declared.

/** Open a handle to an existing persistent key.
*
* Open a handle to a persistent key. A key is persistent if it was created
* with a lifetime other than #PSA_KEY_LIFETIME_VOLATILE. A persistent key
* always has a nonzero key identifier, set with psa_set_key_id() when
* creating the key. Implementations may provide additional pre-provisioned
* keys that can be opened with psa_open_key(). Such keys have an application
* key identifier in the vendor range, as documented in the description of
* #psa_key_id_t.
*
* The application must eventually close the handle with psa_close_key() or
* psa_destroy_key() to release associated resources. If the application dies
* without calling one of these functions, the implementation should perform
* the equivalent of a call to psa_close_key().
*
* Some implementations permit an application to open the same key multiple
* times. If this is successful, each call to psa_open_key() will return a
* different key handle.
*
* \note This API is not part of the PSA Cryptography API Release 1.0.0
* specification. It was defined in the 1.0 Beta 3 version of the
* specification but was removed in the 1.0.0 released version. This API is
* kept for the time being to not break applications relying on it. It is not
* deprecated yet but will be in the near future.
*
* \note Applications that rely on opening a key multiple times will not be
* portable to implementations that only permit a single key handle to be
* opened. See also :ref:\`key-handles\`.
*
*
* \param key The persistent identifier of the key.
* \param[out] handle On success, a handle to the key.
*
* \retval #PSA_SUCCESS
* Success. The application can now use the value of `*handle`
* to access the key.
* \retval #PSA_ERROR_INSUFFICIENT_MEMORY
* The implementation does not have sufficient resources to open the
* key. This can be due to reaching an implementation limit on the
* number of open keys, the number of open key handles, or available
* memory.
* \retval #PSA_ERROR_DOES_NOT_EXIST
* There is no persistent key with key identifier \p id.
* \retval #PSA_ERROR_INVALID_ARGUMENT
* \p id is not a valid persistent key identifier.
* \retval #PSA_ERROR_NOT_PERMITTED
* The specified key exists, but the application does not have the
* permission to access it. Note that this specification does not
* define any way to create such a key, but it may be possible
* through implementation-specific means.
* \retval #PSA_ERROR_COMMUNICATION_FAILURE
* \retval #PSA_ERROR_CORRUPTION_DETECTED
* \retval #PSA_ERROR_STORAGE_FAILURE
* \retval #PSA_ERROR_BAD_STATE
* The library has not been previously initialized by psa_crypto_init().
* It is implementation-dependent whether a failure to initialize
* results in this error code.

* and free all associated resources, just like psa_destroy_key().
*
* If this is the last open handle to a persistent key, then closing the handle
* will free all resources associated with the key in volatile memory. The key
* data in persistent storage is not affected and can be opened again later
* with a call to psa_open_key().
*
* Closing the key handle makes the handle invalid, and the key handle
* must not be used again by the application.
