[PATCH] rtc: armada38x: Remove the unused variables

[PATCH] rtc: armada38x: Remove the unused variables

[Gregory CLEMENT]

When applying the fix "rtc: armada38x: Fix concurrency access in
armada38x_rtc_set_time", some spinlock using the flags variable have
been removed, but not the flags variable themselves. This commit fixes
it.
