Currently each mpc512x board has its own LAW and CS config code, we should avoid this code duplication. Allow all boards to use common code by only defining LAW and CS config macros like CONFIG_SYS_CSx_START, CONFIG_SYS_CSx_SIZE and CONFIG_SYS_CSx_CFG.

Also allow common configuration of additional CS parameters by CONFIG_SYS_CS_ALETIMING, CONFIG_SYS_CS_BURST, CONFIG_SYS_CS_DEADCYCLE and CONFIG_SYS_CS_HOLDCYCLE options.
