Remove AMD special case for LAPIC based udelay()
- Optionally override FSB clock detection in generic
LAPIC code with constant value.
- Override on AMD Model fxx, 10xxx, agesa CPUs with 200MHz
- compile LAPIC code for romstage, too
- Remove #include ".../apic_timer.c" in AMD based mainboards
- Remove custom udelay implementation from intel northbridges' romstages
Future work:
- remove the compile time special case
(requires some cpuid based switching)
- drop northbridge udelay implementations (i945, i5000) if
not required anymore (eg. can SMM use the LAPIC timer?)
