Begining of interrupt (BOI) is only supported on systems with a 8259
interrupt controller all modern x86 systems use APIC interrupt
controller.

This avoids the case where the system has multiple threads using
floating point and the threads were not properly configured to use
floating point. The misconfigured threads will only take the fault on
first use of a floating point instruction.

slower. It's unset by default, but some arch exposing legacy UART ports

The Kconfig option PROT_MODE_SWITCH_PROMPT was being used to conditionally
display the "Boot Sequence Options" Kconfig menu. It is simpler to include
both PROT_MODE_SWITCH and its dependent BOOT_A20_ENABLE in the parent menu.
However, doing so necessitates that the name of the parent menu be changed
from "Bootloader Options" to "Boot Options".

The top-level menus "x86 Core Options" and "Bus Options (PCI etc.)" are now
sub-menus to the the top-level menu "General Platform Configurations".
Also, the "Board Capabilities" sub-menu has been hoisted out of the
"x86 Core Options" menu and placed as a renamed sub-menu
(Platform Capabilities) to the top-level "General Platform Configurations"
menu.
This helps to create a more logical flow when using "make menuconfig".

5. Removes CPU_MINUTEIA selection to permit CPU_ATOM as a valid choice.
