Fix the resolution of dependencies on HMAC

Browse Source 
The Mbed TLS implementations of ALG_TLS12_PRF,
ALG_TLS12_PSK_TO_MS, ALG_HKDF, ALG_HKDF_EXTRACT,
ALG_HKDF_EXPAND and ALG_PBKDF2 rely on HMAC
operations through the driver interface. Thus
if one of these algorithms is enabled and not
accelerated, we need ALG_HMAC to be enabled
(PSA_WANT_ALG_HMAC and PSA_WANT_KEY_TYPE_HMAC
defined). As HMAC operations occur through
the driver interface, HMAC operations can be
accelerated even if the caller algorithm
is not.
