This patch allow to override CONFIG_SYS_TCLK from board configuration files. This is needed for the Network Space v2 which use a non standard core clock frequency (166MHz instead of 200MHz for a 6281 SoC). As a possible enhancement for 6281 and 6282 devices, TCLK could be dynamically detected by checking the Sample at Reset register bit 21. Additionally this patch fix a typo.
