TBBR: Reduce size of ECDSA key buffers
The TBBR implementation extracts public keys from certificates and stores them in static buffers. DER-encoded ECDSA keys are only 91 bytes each but were each allocated 294 bytes instead. Reducing the size of these buffers saves 609 bytes of BSS in BL2 (294 - 91 = 203 bytes for each of the 3 key buffers in use). Also add a comment claryfing that key buffers are tailored on RSA key sizes when both ECDSA and RSA keys are used.
