[PATCH 2/2] clksrc: delete nomadik MTU non-DT boot path

[PATCH 2/2] clksrc: delete nomadik MTU non-DT boot path

[Linus Walleij]

Both platforms using the MTU (Nomadik and Ux500) have now been
converted to use device tree exclusively, thus let us delete
this platform data header and make this driver a fully
self-contained DT-only driver.

Daniel/tglx: seeking an ACK from either of you guys to take this
in the ux500-devicetree branch where the last user is deleted.

A sidenote: there is a comment in arch/arm/mach-ux500/timer.c
"/* TODO: Once MTU has been DT:ed place code above into else. */"
but I did not see any changes related to this TODO.
