exynos5250/snow: deprecate time.h
time.h We Hardly Knew Ye.
This deprecates time.h which is currently only used by Exynos5250 and
Snow. The original idea was to try and unify some of the various timer
interfaces and has been supplanted by the monotonic timer API.
timer_us() is now obsolete. timer_start() is now mct_start() and
is exposed in exynos5250/clk.h.
