[PATCH] x86-64: Try multiple timer variants in check_timer
Instead of adding all kinds of more quirks try various timer
routing variants in check_timer.
In particular this tries to handle quirks from:
- Nvidia NF2-4 reference BIOS: wrong timer override
- Asus: Wrong timer override but no HPET table
- ATI: require timer disabled in 8259
- Some boards: require timer enabled in 8259
We just try many of the the known variants in the hopefully right order
in check_timer.
Trying pin 0/2 on Nvidia suggested by Tim Hockin.
TBD Experimental. Needs a lot of testing
