1927b3d020 gen_isr_tables: New static interrupt build mechanism
This is a new mechanism for generating interrupt tables which will
be useful on many architectures. It replaces the old linker-based
mechanism for creating these tables and has a couple advantages:

 1) It is now possible to use enums as the IRQ line argument to
    IRQ_CONNECT(), which should ease CMSIS integration.
 2) The vector table itself is now generated, which lets us place
    interrupts directly into the vector table without having to
    hard-code them. This is a feature we have long enjoyed on x86
    and will enable 'direct' interrupts.
 3) More code is common, requiring less arch-specific code to
    support.

This patch introduces the common code for this mechanism. Follow-up
patches will enable it on various arches.

8ac992bfcd quark_se: Save/restore debug registers.
In order to set breakpoints after waking up from sleep,
it is needed to save DR0/DR1/DR2/DR3 and DR6/DR7.

As DR4/DR5 are reserved or mapped to DR6/DR7, they are not saved.

Patch2 : Added compile time checks for debug build or soc_watch
build for Intel Energy analysis.

Patch3 : Avoid clobbering of edx.

bb063164aa dts: Add support for Device Tree
This patch adds support for using device tree configuration files for
configuring ARM platforms.

In this patch, only the FLASH_SIZE, SRAM_SIZE, NUM_IRQS, and
NUM_IRQ_PRIO_BITS were removed from the Kconfig options.  A minimal set
of options were removed so that it would be easier to work through the
plumbing of the build system.

It should be noted that the host system must provide access to the
device tree compiler (DTC).  The DTC can usually be installed on host
systems through distribution packages or by downloading and compiling
from https://git.kernel.org/pub/scm/utils/dtc/dtc.git

This patch also requires the Python yaml package.
