config: consolidate CONFIG_SYS_HZ definition

Browse source 
According to the README, CONFIG_SYS_HZ must be 1000 and most platforms
follow that. In preparation to remove CONFIG_SYS_HZ from all these
platforms, provide a common definition. The platforms which use a value
other than 1000 will get build warning now. These configs are:

include/configs/M5271EVB.h:#define CONFIG_SYS_HZ                        1000000
include/configs/balloon3.h:#define      CONFIG_SYS_HZ                   3250000         /* Timer @ 3250000 Hz */
