+read_current_timer is used in the get_cycles() function when
+ARM_ARCH_TIMER is set, and that function can be inlined into
+driver modules, so we should export the function to avoid
+errors like

+ERROR: "read_current_timer" [drivers/video/udlfb.ko] undefined!
+ERROR: "read_current_timer" [crypto/tcrypt.ko] undefined!
