[POWERPC] 83xx: Don't call ioremap in the reset function
It's possibly that we get an reset requestion when interrupts are disabled. (For example an oops in an interrupt handler). Therefor, we can't call ioremap in the reset function. Moving the ioremap of the registers we need access to an arch_initcall helps the problem. However we still have a window between boot and the arch_initcall in which the register pointer will not be setup and thus we spin if the reset function is called. If one needs to ensure even this case is covered, look at use of the watchdog provided on 83xx to reset the processor. Signed-off-by: Kumar Gala <galak@kernel.crashing.org>
