Subject: [PATCH 2/2] time: remove the unnecessary CONFIG_GENERIC_CLOCKEVENS check

In kernel/time/Kconfig:
config GENERIC_CLOCKEVENTS_BUILD
	bool
	default y
	depends on GENERIC_CLOCKEVENTS

So there is no need to check CONFIG_GENERIC_CLOCKEVENTS if the
CONFIG_GENERIC_CLOCKEVENTS_BUILD is defined already.

This prepares for the total removal of GENERIC_CLOCKEVENTS_BUILD.
