Remove all the unwanted exports from the driver

I'm adding event capture capability to the pwm-omap driver and so far used
v4.15-rc3 as codebase.

Intended use is an IR receiver; for that I need to measure pulses width and
spaces between pulses. So DM timer was setup to generate interupt after
both TCAR1 and TCAR2 are filled, values are passed to IR decoder and
TCAR_IT_FLAG is cleared.

Of course, this is just proof of concept and needs to be polished and
generalized, but to make it at least work I need functions you just
unexported (plus some new).

Question is whenever we need this level of indirection (omap_dm_timer_ops)
or plain exports are enough.

The general guidance is not to do plain exports and go via
omap_dm_timer_ops.

...in contrary what other clocksource drivers are doing.

Now I'm assuming it is okay to extend omap_dm_timer_ops. That would mean
check for ops members to be assigned should be also extended or we should
delete it altogether and assume all members are populated?

Thanks,
