[PATCH v4 01/03] clocksource: Add Kconfig entries for CMT, MTU2, TMU and STI

[Magnus Damm]

From: Magnus Damm <damm@xxxxxxxxxxxxx>

Add Kconfig entries for CMT, MTU2, TMU and STI to
drivers/clocksource/Kconfig. This will allow us to
get rid of duplicated entires in architecture code
such as arch/sh and arch/arm/mach-shmobile.
