When using TF-M, use the PSA_KEY_TYPE_ECC_KEY_PAIR() macro from
mbedtls_psa_parse_tls_ecc_group(), since that function is supposed to
return a psa_key_type_t. This helps to avoid any misencodings when the
return value from mbedtls_psa_parse_tls_ecc_group() is used directly as
a psa_key_type_t without additional encoding.

When using TF-M, be sure to specify the length of the key.

Fixes: 0961f312c6b0 ("Make PSA util compatible with Mbed Crypto 3.0.1")

Mbed Crypto 3.0.1 ships with TF-M. To make Mbed TLS 2.22.0 compatible
with Mbed Crypto 3.0.1, changes are needed in psa_util.h (which
abstracts some portions of the PSA Crypto API for use with TLS) to deal
with new ECC curve define changes.
