armv7/snow: Move clock initialization from bootblock to romstage.
Exynos system clock can be initialized before RAM init, not necessary to be in
the very beginning (boot block). This helps reducing bootblock dependency.
Verified to boot on armv7/snow.
Note: this patch was originally introduced in 2308, but there were
some ordering issues so it was reverted.
