SPM: Replace SP init flag by generic state enum

Instead of just knowing if the Secure Partition is being initialized or
not, this generic state enum can be used to tell if the Secure Partition
is busy and to add more states in the future if needed.

Also, the spinlock of the secure_partition_context_t structure now only
protects against concurrent accesses to the state of the secure
partition. Previously, it used to lock down the whole structure, thus
preventing one CPU to access any of its fields while another CPU was
executing the partition.
