New init levels introduced: PRE_KERNEL_1, PRE_KERNEL_2, POST_KERNEL
to replace them.
Most existing code has instances of PRIMARY replaced with PRE_KERNEL_1,
SECONDARY with POST_KERNEL as SECONDARY has had a longstanding bug
where the documentation specified SECONDARY ran before the kernel started
up, but actually ran afterwards.

Making a reference to the common work queue code should not necessarily
drag in the system workqueue, since it is possible to use a workqueue
that is not the system workqueue. This is done by moving the system
workqueue into its own code module.
Moving the system workqueue to its own code module allows removing the
NANO_WORKQUEUE and SYSTEM_WORKQUEUE kconfig options, and compiling the
common workqueue code and system workqueue all the time. They are only
linked in the final image if a reference to them exist, same as the
other kernel modules.

Adds basic sensor driver support for the NXP FXOS8700 6-axis
accelerometer/magnetometer. Currently this driver supports
accelerometer-only, magnetometer-only, and hybrid (accelerometer +
magnetometer) modes, as well as 2g, 4g, and 8g accelerometer full scale
ranges.
This driver does not yet support any sensor triggers such as the data
ready trigger, or runtime changing of sensor attributes.
