Remove dependency between SPM_MM and ENABLE_SPM build flags
There are two different implementations of Secure Partition management in TF-A. One is based on the "Management Mode" (MM) design, the other is based on the Secure Partition Client Interface (SPCI) specification. Currently there is a dependency between their build flags that shouldn't exist, making further development harder than it should be. This patch removes that dependency, making the two flags function independently. Before: ENABLE_SPM=1 is required for using either implementation. By default, the SPCI-based implementation is enabled and this is overridden if SPM_MM=1. After: ENABLE_SPM=1 enables the SPCI-based implementation. SPM_MM=1 enables the MM-based implementation. The two build flags are mutually exclusive. Note that the name of the ENABLE_SPM flag remains a bit ambiguous - this will be improved in a subsequent patch. For this patch the intention was to leave the name as-is so that it is easier to track the changes that were made.
