    hardwaremain: Move init_timer() call to before console init
    
    The 8250 MMIO uart driver calls udelay, and if that is the first
    call then it will also call printk in init_timer() which can result
    in a deadlock trying to acquire the console lock.
    
    There are a few options to prevent this:
    1) remove the printk in init_timer which removes a useful debug message
    2) change the udelay() to cpu_relax() in uart8250mem.c
    3- move the init_timer() call in ramstage main() to be called earlier
    
    Since hardwaremain.c:main() already has an explicit call to init_timer()
    on x86 it is an easy change to move this to happen before the console
    is initialized.
