watchdog: sirf: don't depend on dummy value of CLOCK_TICK_RATE
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. Signed-off-by: Uwe Kleine-König <u.kleine-koenig@pengutronix.de> Signed-off-by: Wim Van Sebroeck <wim@iguana.be>
