[PATCH] clocksource: efm32: let CLKSRC_EFM32 select CLKSRC_OF

[u.kleine-koenig@pengutronix.de (Uwe Kleine-König)]

The efm32 timer driver is only usable with CLKSRC_OF, so it makes sense
to let its Kconfig symbol select it. For compile coverage testing it's not
needed though, so only select it if ARCH_EFM32 is enabled.

This allows to drop ARCH_EFM32 selecting CLKSRC_OF which is done here
for simplicity, too.
