When booting a recent Linux kernel, the qemu message "Timer with delta
zero, disabling" is seen, apparently because a ptimer is started before
being initialized. Fix the problem by initializing the offending ptimer
before starting it.
The bug is effectively harmless in the old QEMUBH setup
because the sequence of events is:
* the delta zero means the timer expires immediately
* ptimer_reload() arranges for exynos4210_gfrc_event() to be called
* ptimer_reload() notices the zero delta and disables the timer
* later, the QEMUBH runs, and exynos4210_gfrc_event() correctly
configures the timer and restarts it
In the new transaction based API the bug is still harmless,
but differences of when the callback function runs mean the
message is not printed any more:
* ptimer_run() does nothing as it's inside a transaction block
* ptimer_transaction_commit() sees it has work to do and
calls ptimer_reload()
* the zero delta means the timer expires immediately
* ptimer_reload() calls exynos4210_gfrc_event() directly
* exynos4210_gfrc_event() configures the timer
* the delta is no longer zero so ptimer_reload() doesn't complain
(the zero-delta test is after the trigger-callback in
the ptimer_reload() function)
Regardless, the behaviour here was not intentional, and we should
just program the ptimer correctly to start with.
