There is no point in having an extra type for extra confusion. u64 is
unambiguous.
Conversion was done with the following coccinelle script:

Because the PIT is also a proper clocksource, the timekeeping code is
already able to handle lost ticks.

The previous fix introduced a check against the ret variable which
is not defined, hence producing a compilation error:
linux/drivers/clocksource/timer-atmel-pit.c: In function ‘at91sam926x_pit_dt_init’:
linux/drivers/clocksource/timer-atmel-pit.c:264:2: error: ‘ret’ undeclared (first use in this function)
ret = clk_prepare_enable(data->mck);
^
linux/drivers/clocksource/timer-atmel-pit.c:264:2: note: each undeclared identifier is reported only once for each function it appears in
Add the missing the variable 'ret'.

mck is needed to get the PIT working. Explicitly prepare_enable it instead
of assuming it is enabled.
This solves an issue where the system is freezing when the ETM/ETB drivers
are enabled.

All the clocksource drivers's init function are now converted to return
an error code. CLOCKSOURCE_OF_DECLARE is no longer used as well as the
clksrc-of table.
Let's convert back the names:
- CLOCKSOURCE_OF_DECLARE_RET => CLOCKSOURCE_OF_DECLARE
- clksrc-of-ret => clksrc-of

The init functions do not return any error. They behave as the following:
- panic, thus leading to a kernel crash while another timer may work and
make the system boot up correctly
or
- print an error and let the caller unaware if the state of the system
Change that by converting the init functions to return an error conforming
to the CLOCKSOURCE_OF_RET prototype.
Proper error handling (rollback, errno value) will be changed later case
by case, thus this change just return back an error or success in the init
function.

Migrate atmel 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.
