score: Delete _CPU_Context_Fp_start()

Since the FP area pointer is passed by reference in
_CPU_Context_Initialize_fp() the optional FP area adjustment via
_CPU_Context_Fp_start() is superfluous.  It is also wrong with respect
to memory management, e.g. pointer passed to _Workspace_Free() may be
not the one returned by _Workspace_Allocate().

Close #1400.

- * The purpose of this macro is to allow the initial pointer into
- * a floating point context area (used to save the floating point
- * context) to be at an arbitrary place in the floating point
- * context area.
- *
- * This is necessary because some FP units are designed to have
- * their context saved as a stack which grows into lower addresses.
- * Other FP units can be saved by simply moving registers into offsets
- * from the base of the context area.  Finally some FP units provide
- * a "dump context" instruction which could fill in from high to low
- * or low to high based on the whim of the CPU designers.
- *
- * @param[in] _base is the lowest physical address of the floating point
- *        context area
- * @param[in] _offset is the offset into the floating point area
