The ticker was always initialized in the NANOKERNEL init level. In a
microkernel, this can cause problems if for the some reason the
initialization of the microkernel server is delayed, such as devices
initialization in the NANOKERNEL level taking non-insignificant time to
complete. What happens in that case is the ticker ISR will start firing
and piling up events in the microkernel server stack, and quite quickly
overrun it, since it has a finite size, causing random crashes.
So, in the microkernel, initialize the ticker once the microkernel
server is available. There is no point in sending ticker event before
anyway.

TICKS_NONE was mistakenly used when waiting on the nanokernerel
semaphore in the microkernel case, instead of TICKS_UNLIMITED, causing a
thread that wants to wait to return immediately, as if the device was
always ready.

Before this fix, a call to the API read() method could unexpectedly

Per Curie documentation, the first sample from the Quark SE ADC
hardware after reset needs to be dropped.
This commits changes the location and the trigger event to do
a dummy read that drops the first sample.
Originally the driver did the dummy read on the API call enable()
and it was triggered if the ADC had awakened from suspend mode.
Because the SoC is not in suspend mode on power on and the API
enable() call has no information on the channels to be read the
dummy read could be missed.
Now the dummy read is done on the API call to read()
and triggered if it is the first time read() is called
since power on.

Having priority levels 0 and 1 reserved on x86 due to implementation
details on how the CPU uses the vector table is confusing to users,
and makes it unnecessarily difficult to share drivers between arches.
Now on x86, priority levels 0 and 1 are available. Semantically, all
priority levels have had 2 subtracted from them.
It is no longer necessary to specify a priority level when the
vector itself is specified. If an IDT entry has a specific vector
associated with it, any priority argument is simply ignored.
In gen_idt, some simplifications have been made:
- The printed representation of a generated entry now fits on one line
- Some checks being done in validate_priority() were redundant, as
generate_interrupt_vector_bitmap() also ensures that there are
sufficient free vectors within a priority level.

If an init or config function needs to configure a static interrupt or
otherwise do something that requires a build time reference to
a device with DEVICE_GET(), there is a dependency issue that so
far is usually resolved with a forward prototype of the init function.
In addition, there currently isn't a good way to declare a device in
a header so that DEVICE_GET() can be used in a different C file.
This patch should resolve both of these problems; the data structure
defined for the device is no longer static (the names have to be unique
anyway), and in cases where we need a forward declaration so that
DEVICE_GET() can be used, we have a new DEVICE_DECLARE() macro which
does this.

The argument to _common_dynamic_exc_handler() in the C domain
was still being set up the Sys V way. Arguments are popped off the
stack in reverse order, so _ExcEnt pushes *pEsf for arg 2, and then
the stub pushes the stub_num for Arg 1.
For IAMCU case, *pEsf is placed in EAX which is where argument 1
lives; static exception handlers take just one argument. However
since we're calling _common_dynamic_exc_handler we also need to
supply the stub_id, which we put in EDX (where arg 2 goes).
Rather than swapping things around at runtime the prototype for
_common_dynamic_exc_handler() is adjusted to fit the calling
convention in use.

As the GPIO callback is ran into ISR context, it's thus impossible to
start SPI transactions as these are interrupt based as well. Thus
forwarding the packet reading to an internal fiber.
If CONFIG_INIT_STACKS is set as well as debug mode, it will print out
the usage of the stack after each loop in read_packet().
CC2520 internal fiber stack size is set via Kconfig option, where the
default is set to 640 bytes. At this stage, this value cannot be fixed
so it's more flexible to be able to tweak it from a Kconfig option
rather than tweaking the source code.
