i386: Always set LINTEN for AMD CPUs if their family >= 0xF

Since LINTEN will take effect when LAPIC is hardware enabled,
so we defer the LINTEN turning on when we know LAPIC will be
software enabled.

This fixes the recent MI per-cpu interrupt information array
support on AMD CPUs when IOAPIC is disabled on SMP system.
