Subject: [PATCH] clocksource/drivers/sprd: Fix Kconfig dependency

SPRD arch doesn't select SPRD_TIMER, so this config would not
appear even if ARCH_SPRD is set and COMPILE_TEST is not.

Fix the Kconfig selection rule by letting the SPRD arch to select.

This patch also sets the default value of SPRD_TIMER with ARCH_SPRD,
but it still is selectable to users.
