Juno: Bump up the BL1-RW size

This patch bumps up the BL1-RW size for Juno and at the same time reduces
the BL2 size when TBB is enabled, TF_MBEDTLS_KEY_ALG=rsa+ecdsa. The BL2
size for this config is reduced as it was observed that the peak memory
usage is only reached when SPD=opteed and the dual rsa+ecdsa support is
not needed for this case.
