[ Upstream commit 36c47df85ee8e1f8a35366ac11324f8875de00eb ]
clang produces a build failure in configurations without COMMON_CLK when a timeout calculation goes wrong:
arm-linux-gnueabi-ld: drivers/watchdog/coh901327_wdt.o: in function `coh901327_enable': coh901327_wdt.c:(.text+0x50): undefined reference to `__bad_udelay'
Add a Kconfig dependency to only do build testing when COMMON_CLK is enabled.
