This function sets the PB divider, the Flash Wait States, and the DRM
/wait states to the optimum value. It also enables the cacheability for
the K0 segment. It could has side effects of possibly alter the pre-fetch
buffer and cache. It sets the RAM wait states to 0. Other than
the SYS_FREQ, this takes these parameters. The top 3 may be '|'ed
together:
SYS_CFG_WAIT_STATES (configures flash wait states from system clock)
SYS_CFG_PB_BUS (configures the PB bus from the system clock)
SYS_CFG_PCACHE (configures the pCache if used)
SYS_CFG_ALL (configures the flash wait states, PB bus, and pCache)*/
