Introduce the new kernel sub-tree x86 which should contain all the code shared and generalized between our current amd64, i386 and pc98.
This is just an initial step that should lead to a more complete effort. For the moment, a very simple porting of cpufreq modules, BIOS calls and the whole MD specific ISA bus part is added to the sub-tree but ideally a lot of code might be added and more shared support should grow.

Tweak the ELCR support slightly. Explicitly probe the ELCR during boot instead of burying that in the atpic(4) code as atpic(4) is not the only user of elcr(4). Change the elcr(4) code to export a global elcr_found variable that other code can check to see if a valid ELCR was found.

Add a simple mini-driver for the ELCR register. Originally, the ELCR register controlled the trigger mode and polarity of EISA interrupts. However, it appears that most (all?) PCI systems use the ELCR to manage the trigger mode and polarity of ISA interrupts as well since ISA IRQs used to route PCI interrupts need to be level triggered with active low polarity. We check to see if the ELCR exists by sanity checking the value we get back ensuring that IRQS 0 (8254), 1 (atkbd), 2 (the link from the slave PIC), and 8 (RTC) are all clear indicating edge trigger and active high polarity.
This mini-driver will be used by the atpic driver to manage the trigger and polarity of ISA IRQs. Also, the mptable parsing code will use this mini driver rather than examining the ELCR directly.
