ta: pkcs11: Add function to set key data

Earlier derive_key_by_symm_enc() was used to derive key
by cipher operation and set the derived key value in
the object attributes. Simplify it to just derive the
key and return the derived key value to calling function.
Separate function is created to add this derived key value
in the key object.

ta: pkcs11: Fix interpretation of CKA_VALUE_LEN for Generic Secrets

ta: pkcs11: Fix interpretation of CKA_VALUE_LEN for Generic Secrets

PKCS#11 specification [1] section 2.6.3 states that - For
CKM_GENERIC_SECRET_KEY_GEN mechanism, the ulMinKeySize and
ulMaxKeySize fields of the CK_MECHANISM_INFO structure
specify the supported range of key sizes, in bits.

Based on this, assumption was being made in the code that key length
specified by CKA_VALUE_LEN for keys of type CKK_GENERIC_SECRET is also
in bits. This assumption is not correct as per Section 2.6.2 in [1].
Special handling in code for CKK_GENERIC_SECRET for handling keysize
in bits has been now removed.

ta: pkcs11: Add support for big key sizes for HMAC hash Mechanisms

Currently the support for maximum key size supported in HMAC hash
functions is limited by the underlying Global TEE implementation.
The RFC 2202 and 4231 specify some HMAC test vectors where key size
is greater than the sizes as supported in current TEE implementation.
For such key sizes, greater than the maximum key size supported by TEE,
first hash the key and then use the resultant as the actual key to
HMAC.
