rtems: Simplify semaphore configuration
The MrsP semaphore implementation predates the addition of
self-contained synchronization objects. At this time, the potential
memory reduction was justified considering the more complex
configuration and additional use of the workspace. With the
availability of self-contained synchronization options, e.g. POSIX
mutexes, this is no longer justified. Memory constrained applications
should use the self-contained synchronization objects. Remove the
CONFIGURE_MAXIMUM_MRSP_SEMAPHORES configuration option. This has only an
impact on applications which use SMP and a large number of scheduler
instances.
Update #3833.
