[patch V2 01/10] timer: Invoke timer_start_debug() where it makes sense

[-- Attachment #1: timer--call-debug-function-after-setting-properly-the-base-and-the-flags.patch --]
[-- Type: text/plain, Size: 834 bytes --]

The timer start debug function is called before the proper timer base
is set.

As a consequence the trace data contains the stale CPU and flags values.

Call the debug function after setting the new base and flags.
