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().

The "__stack" tag is to be used to align an array (to STACK_ALIGN) for stack

Completes the renaming of nanoFiberStart() -> fiber_fiber_start().
There is little value in listing the callers of _NewContext() in its function
header. Not only was the (deleted) list both incomplete and wrong, keeping
it around and properly updated requires error prone maintenance.

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.
