Andre Guedes ec7c6a80fc i2c: Enable QMSI driver for Quark D2000
This patch fixes the QMSI I2C shim driver so we are able to use it in
Quark D2000 based platforms. The only change required to enable this
driver is an #if guard in i2c_qmsi_init() because the macro QM_I2C_1
is not defined in QMSI headers from Quark D2000.

Since this drivers is now properly tested with Quark D2000, this patch
sets the QMSI driver default options in arch/x86/soc/quark_d2000/Kconfig.
It also adds the wiring information required to test the i2c_lsm9ds0
sample app in the Quark D2000 CRB.

I2C LSM9DS0 Sample Application
==============================

This sample application illustrates how to use I2C APIs from Zephyr.
It requires an external device in order to work. The external device
is the accelerometer from LSM9DS0. The datasheet can be found in:
https://www.adafruit.com/datasheets/LSM9DS0.pdf

The application is very simple. It simply reads the 'WHO AM I' register
from the accelerometer and check if matches with the value described in
the datasheet.

Below follows the wiring information for each board this samples has been
tested.
