[U-Boot] [PATCH] README: document the requirements for CONFIG_SYS_HZ

Dear Stephen,

In message <1363923692-12748-1-git-send-email-swarren@wwwdotorg.org> you wrote:

"must return mS" ? "mS" means Milli-Siemens, which is a unit of
electric conductance and electric admittance.  You mean "ms" =
milliseconds ...

This is misleading, or even incorrect.  If I read this, I would expect
that get_timer() returns 1000. Obviously, this is incorrect.  Instead,
get_timer() returns timestamp information in millisecond resolution.
