When generating a DSA key, syscall_obj_generate_key() currently ignores
the supplied parameters: TEE_ATTR_DSA_PRIME, TEE_ATTR_DSA_SUBPRIME and
TEE_ATTR_DSA_BASE. Instead a new set of parameters is generated each
time based on the specified key size. This does not comply with the
GlobalPlatform TEE Internal Core API specification which lists these
atrributes as mandatory input to the generation function (see v1.2.1
table 5-12 TEE_GenerateKey parameters).
Fix this issue by providing the supplied parameters to LibTomCrypt's
dsa_generate_key() instead of calling dsa_make_key().
