mpc83xx: Fix config of Arbiter, System Priority, and Clock Mode
The config value for: * CFG_ACR_PIPE_DEP * CFG_ACR_RPTCNT * CFG_SPCR_TSEC1EP * CFG_SPCR_TSEC2EP * CFG_SCCR_TSEC1CM * CFG_SCCR_TSEC2CM Were not being used when setting the appropriate register Added: * CFG_SCCR_USBMPHCM * CFG_SCCR_USBDRCM * CFG_SCCR_PCICM * CFG_SCCR_ENCCM To allow full config of the SCCR. Also removed random CFG_SCCR settings in MPC8349EMDS, TQM834x, and sbc8349 that were just bogus. Signed-off-by: Kumar Gala <galak@kernel.crashing.org>
