This adds a simple driver with the only purpose to initialise
the fixed rate clock.
This is useful for systems that do not wish to use seperate init
code for the fixed rate clock init, but rather only rely on a
device tree description of it.

By slightly reorganizing the code, the number of registers
used in the tlb miss handlers can be reduced by two,
thus removing the need to save them to memory.
Also, some dead and commented out code is removed.

A signal delivered through do_notify_resume() would cause the

Enable interrupts before calling do_notify_resume(), but read
the current_thread_info->flags before doing so.
