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

BOOT_A20_ENABLE relies on the kernel being on a system that has a full
PC BIOS and requires that the A20 line be enabled to boot
correctly. None of the supported platforms satisfy either requirment.

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.

All supported platforms have descending stack (growth direction is
down). To avoid confusion just remove not needed stack direction
defines.
If new platform with stack direction up is added is should be
configured by adding Kconfig option eg STACK_GROWS_UP and
CONFIG_STACK_GROWS_UP should be used in code that depends on
stack growth direction.

There are devices that need are part of the architecture core the need
to be initialized prior to devices that are integrated around a core
to make up a complete SOC. Namely the interrupt controller in the SOC
must be configured in order to allow the integrated IP blocks drivers
to initialize correctly.

Those ports uses different instructions to get accessed: in/out
instructions. It differs in many ways with memory access, and it's much
slower. It's unset by default, but some arch exposing legacy UART ports
might need it.
