We can now use the Device Tree for bringing up our timer device CMT10 on
the SoC sh73a0.

v2:
- Moved the definition from the board .dts to the SoC .dtsi
- Renamed cmt@0xe6138010 to timer@e6138010

I didn't test this patch,
but setup-sh73a0.c :: sh73a0_devices_dt is
used from sh73a0_add_standard_devices() or sh73a0_add_early_devices(),
and it is used from board-kzm9g.c (not -reference.c).

Does board-kzm9g.c still works ?
Is it better that sh73a0_early_devices[] has it ?


Best regards

As the timer devices have no board dependencies we can put them into
the general sh73a0.dtsi and it works for the reference and
no-reference case.

Still - while rechecking it I discovered a small slip I made in my
series. In 0003-Add OF to TMU I forgot 2 trivial lines. So thanks for
asking ;)

Cheers,

 Bastian
