b04958a006 platforms: introduce Quark X1000 SoC
The Galileo board is based on the X1000 SoC, so move galileo to
boards and create this SoC instead, inheriting all SoC related code
and configuration items.

90102a97d2 curie-101 : pinmux : mapping in the SPI1
According to the schematic, SPI1_M_ should be properly mapped out
on the pinmux.  This should enable the SPI1_M functionality on the
Arduino / Genuino 101 board now.

34d3d9e971 pinmux : quark_se / quark_d2000 : reducing RAM and ROM
Updating the pinmux to use a local static table for each pin select
option.  Instead moving to a static series of function calls that
move the data from the RAM section to the ROM section.

This impacts only the Quark D2000 and the Quark SE chips.  It does
not show any impact to the basic_minuteia tests.

All said we see small changes that amount to some values like:

933d231cb4 quark: Add compile fences to the quark platforms
Currently the Quark SE and Quark D2000 platform are only included
through the use of a compile fence one level higher in the Makefile.
Adding in a secondary compile fence to ensure if that check ever
changes, we won't be in trouble.

14b5d5c79d quark_se : pinmux : fixing the naming convention
Naming convention should follow the IP_noun_verb concept.  In this case,
renaming several functions from (for example) pinmux_set_pin to
pinmux_pin_set, while also correctly naming the function to their
specific tasks.

This is being done to make way for the ability to change the input
value, pullup value, and the slew as well.

689ec02211 x86: mvic: fix IDT reload
The argument to 'lidt' is a chunk of memory with the base address
and limit of the IDT, and not the IDT itself. Horrible things
were happening when the IDT itself was being passed to this
instruction.

To be extra safe, disable interrupts while we modify the table
and subsequently reload it.

a664aae335 x86: reduce static IRQ stub size
All of these stubs at the end pop the stack and tell the LOAPIC
that we are at EOI. Put this in common code which falls through to
_IntExit(). Saves 8 bytes per static IRQ stub. There is also small
constant savings in the common code for dynamic IRQs.

88808f1247 quark_se: apic: work around EOI forwarding issue
Quark SE Lakemont core has a hardware bug where the LOAPIC does
not properly notify the IOAPIC to clear the IRR bit for level-
triggered interrupts.

This patch introduces a workaround where the vector ID of the
in-service interrupt is manually written to the IOAPIC_EOI
register, resulting in the bit being cleared.

Unfortunately, in the context where EOI happens it's very difficult
to identify which IRQ line is being serviced, so this is done
unconditionally for all interrupts vectors whether they are registered
in the IOAPIC RTE table or not.

(due to arch/x86/Kbuild), which requires building some object
files. So the empty source files are there to produce empty
