kconfig: move CONFIG_SYS_HZ to lib/Kconfig
CONFIG_SYS_HZ is always defined as 1000 in config_fallbacks.h
(but some boards still have redundant definitions).
This commit moves the definition and the document in README to
Kconfig. Since lib/Kconfig can assure that CONFIG_SYS_HZ is 1000,
the sanity check in lib/time.c should be removed.
