laurenw-arm 78da42a5f1 refactor(measured-boot): mb algorithm selection ... With RSS now introduced, we have 2 Measured Boot backends. Both backends can be used in the same firmware build with potentially different hash algorithms, so now there can be more than one hash algorithm in a build. Therefore the logic for selecting the measured boot hash algorithm needs to be updated and the coordination of algorithm selection added. This is done by: - Adding MBOOT_EL_HASH_ALG for Event Log to define the hash algorithm to replace TPM_HASH_ALG, removing reference to TPM. - Adding MBOOT_RSS_HASH_ALG for RSS to define the hash algorithm to replace TPM_HASH_ALG. - Coordinating MBOOT_EL_HASH_ALG and MBOOT_RSS_HASH_ALG to define the Measured Boot configuration macros through defining TF_MBEDTLS_MBOOT_USE_SHA512 to pull in SHA-512 support if either backend requires a stronger algorithm than SHA-256.
