drivers: Add infrastructure for QMSI drivers

Browse source 
This patch introduces the infrastructure required to enable QMSI drivers.
QMSI drivers are shim drivers based on drivers provided by QMSI BSP. The
BSP provides a static library (libqmsi) which implements several drivers
for peripherals from Intel MCUs.

Next patch will introduce the first QMSI driver (watchdog driver) which
will rely on the infrastructure introduced by this patch.

config QMSI_DRIVERS
depends on CPU_MINUTEIA
bool "Enable QMSI drivers"
default n
help
This option enables QMSI device drivers. These drivers are actually shim
drivers based on drivers provided by QMSI BSP. The BSP provides a static
library (libqmsi) which implements several drivers for peripherals from
Intel MCUs (e.g. Quark SE and Quark D2000).
config QMSI_INSTALL_PATH
depends on QMSI_DRIVERS
string "QMSI install path"
help
This option holds the path where the QMSI library and headers are
installed. Make sure this option is properly set when QMSI_DRIVERS
is enabled otherwise the build will fail.
