[PATCH] clocksource: sirf/marco+prima2: drop usage of CLOCK_TICK_RATE

[Uwe Kleine-König]

As CSR SiRF is converted to multi platform CLOCK_TICK_RATE is a dummy
value that seems to match the right value is used.
(arch/arm/mach-prima2/include/mach/timex.h which defined CLOCK_TICK_RATE
to 1000000 was removed in commit cf82e0e (ARM: sirf: enable
multiplatform support); marco used the same file.)

To not depend on that dummy value use a local #define instead.
