[ion] 24964: - Fixup all the file headers with proper paths and authors. - Move sysbus.c contents (a 4 line function) into bus.c. - Unify initialization code. - Delete and disable stall execution calibration (currently using the default). Will implement later in a more precise manner (this routine was bizarly setting the MHz of the CPU in the PRCB in some cases...).

Log:
- Fixup all the file headers with proper paths and authors.
- Move sysbus.c contents (a 4 line function) into bus.c.
- Unify initialization code.
- Delete and disable stall execution calibration (currently using the default). Will
implement later in a more precise manner (this routine was bizarly setting the MHz of the
CPU in the PRCB in some cases...).
