i2c: Enable QMSI driver for Quark D2000

Browse source 
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.
