主题: [PATCH] clocksource/drivers/sprd: Remove the dependency between sprd timer and SPRD arch

From: Nianfu Bai <nianfu.bai@...soc.com>

Tick broadcast installed by insmod cannot switch to oneshot mode correctly
caused by linux timer framework, need to build in kernel image. SPRD_TIMER
has been selected by SPRD arch, we have to enable SPRD arch when we build
sprd timer in kernel image, this action conflicts with general kernel image,
so we need to remove the dependency between sprd timer and SPRD arch.
