For the sake of consistency, let rename all ctrl_out/in calls to the write/read
calls so we have the same API consistent with the other architectures hence
open the door for the increasing of the test compilation coverage.
The unsigned long coercive cast is removed because all variables are set to
the right type "void __iomem *".

The current code retrieves the rate value when the timer is enabled which
occurs each time a timer is re-armed. Except if the clock frequency has changed
magically I don't see why this should be done each time.
Retrieve the clock rate value at init time only.

The time framawork takes care of disabling the interrupts and takes a lock
to prevent races.
Remove the legacy code in the driver taking care of the races.

The current code assumes the interrupt function is re-entrant.
That is not correct. An interrupt handler is never invoked concurrently. The
interrupt line is masked on all processors.
Remove the chewing flags in the code.

The value returned in case of error for the 'irq_of_parse_and_map' function is
zero in case of error. Fix the check in the init code.

Specify the delta as parameter for the timer8_clock_event_start function
instead of using a macro to tell PERIODIC or ONESHOT.

The dev_warn is using the platform driver which was removed in the previous
patch.
Let's replace dev_warn by pr_warn.

Remove some legacy code and replace it by the clksrc-of code.
Do some cleanup and code consolidation.

Memory for timer16_priv, timer8_priv and tpu_priv structs is
allocated by devm_kzalloc() in corresponding probe functions
of drivers.
No need to zero it one more time.

Migrate h8300_timer8 driver to the new 'set-state' interface provided by
clockevents core, the earlier 'set-mode' interface is marked obsolete
now.
This also enables us to implement callbacks for new states of clockevent
devices, for example: ONESHOT_STOPPED.
