watchdog: coh901327: add COMMON_CLK dependency

Browse Source 
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.

Fixes: da2a68b3eb ("watchdog: Enable COMPILE_TEST where possible")
