ARM: sa1100: stop using mach/timex.h

Browse Source 
mach/timex.h is the last remaining header that is unused for multiarch
builds but necessary for singlearch builds. To allow to get rid of it
for singlearch builds, too, drop its usage in sa1100 arch code by
substituting CLOCK_TICK_RATE and LATCH by a local cpp symbol.
