Since the system generator pre-registers K_ticker as the handler
for the system tick event, there is no need for the timer driver
to re-register it at run time.

The atomic_get() function is a read-only API which doesn't modify the
value given to it. The input parameter should therefore be declared as
const.

Introduces nano_internal.h, which will declare all architecture-
independent non-public nanokernel APIs. This file is automatically
incorporated by the various architecture-specific include files
for non-public nanokernel APIs, and will not normally be included
directly by any other files.

1) Renames routine to conform to kernel naming conventions.
2) Relocates routine declaration to include files for
non-public nanokernel APIs.
3) Relocates routine definition so that it resides with the
nanokernel's other fiber manipulation routines.
4) Eliminates an unnecessary argument to the routine.

Instead of initializing the stack (when INIT_STACKS is enabled) in start_task()
and _fiber_start(), do it in _NewContext(). This helps to both reduce code
duplication AND ensure that all contexts get an initialized stack (previously
the background/idle task's was missed).

According to section 3.7 of Documentation/kbuild/makefiles.txt, using
EXTRA_CFLAGS in Makefiles is "still supported but their usage is
deprecated." However, using make EXTRA_CFLAGS="-DSOMETHING" results in
EXTRA_CFLAGS from Makefiles being overwritten, obviously breaking the
build. This patch converts to them to the newer ccflags-y which also
fixes the problem.

Since the address of the new context is known before _NewContext() is invoked
(due to it being passed a properly aligned stack), there is no longer any
need for _NewContext to return the pointer to the context.
Furthermore, as a direct result of the properly aligned stack, the pointer to
the new context does not need to be passed as a separate parameter since it
will always match the passed stack pointer.

Runtime alignment of a context's stack is no longer necessary in _NewContext()
as the memory is aligned (via the __stack tag) before calling _NewContext().

UART on Quark platfor, according to Quark BSP Programmer's
Reference Manual, is located in the following order on PCI bus:
COM2 BAR0: 16550 registers
BAR1: DMA registers
COM1 BAR0: 16550 registers
BAR1: DMA registers
So, the driver on Quark platform has to specify BAR (Base
Address Registers) number, the pci_bus_scan() function looks for.
As long as UART is a concole device, calling pci_show() during
it's initialization does not make any output.
