Following recent (and less so) issues with the 8254 timer when routed
through the I/O or local APIC, always report which configurations have
been tried and which one has been set up eventually.  This is so that logs
posted by people for some other reason can be used as a cross-reference
when investigating any possible future problems.

The change unifies messages printed on 32-bit and 64-bit platforms and
adds trailing newlines (removes leading ones), so that proper log level
annotation can be used and any possible interspersed output will not cause
a mess.

I have chosen to use apic_printk(APIC_QUIET, ...) rather than printk(...)
so that the distinction of these messages is maintained making possible
future decisions about changes in this area easier.  A change posted
separately making apic_verbosity unsigned removes any extra code that
would otherwise be generated as a result of this design decision.
