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 function does not return any error, it prints a message, returns and
lets 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 mxs 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.
Also drop:
- 'mxs_clockevent_mode': as we have helpers available from core for the
same.
same state twice and so perhaps the check wasn't required.
- 'clock_event_mode_label': CLOCK_EVT_MODE_* shouldn't be used anymore
by drivers and it was used just to print old-state:new-state. The
debug prints are called from mxs_irq_clear() now based on the
state-name passed to it. The printed name will be same for shutdown
and resume states as they use the same callback pointer.

The 32 bit sched_clock interface now supports 64 bits. Upgrade to
the 64 bit function to allow us to remove the 32 bit registration
interface.

Nothing about the sched_clock implementation in the ARM port is
specific to the architecture. Generalize the code so that other
architectures can use it by selecting GENERIC_SCHED_CLOCK.
