Pass the base offset to the Nomadik MTU timer in the init call
instead of keeping a global pointer to be assigned.

Based on a patch from Arnd Bergmann this fixes up the build
problem of assigning a non-existing global when the ux500 PRCMU
timer is not linked in by passing its base address to the init
function. We also add a missing <linux/errno.h> inclusion and
staticize the dummy function.

On ux500 the MTU timer blocks are powered off during
suspend/resume, so these need some reinitialization when
coming back from suspend.

Just split off the timer code to its own file so we have a
more fine-grained file tree.
