Add a new API to bio layer(read_async) where function will
return immediately, and a callback function will be called from
interrupt context, when block driver completes the IO request.
Some of the structures, notably 'cmd', in the lib console stuff are a
little too generically named and have collided with some other code
so prefix the names a bit more cleanly with console_
The change is largely mechanical, and folks with out of tree code can
easily switch by renaming:
cmd -> console_cmd
cmd_args -> console_cmd_args
cmd_block -> console_cmd_block
console_cmd -> console_cmd_func
Apologies if this breaks you but it should be pretty easy to fix.
Now you need to include arch/atomic.h to get to the atomic routines.
This simplifies a recusion issue in the way arch/ops.h included
arch_ops. Also just generally makes things cleaner.
TL;DR most uses of lib/console.h -> lk/console_cmd.h
Move the part that lets a piece of code somewhere in the system to
define a console command from the actual lib/console api to start an
instance of the console. Move in almost every place the user of the
console command definition to the new header, lk/console_cmd.h which is
always in the include path.
Also remove most uses of testing for WITH_LIB_CONSOLE since you can
almost always just safely define it and then let the linker remove it.
Almost nothing changes here except moving braces to the same line as the
function declaration. Everything else is largely whitespace changes and
a few dangling files with tab indents.

Sub device inherits parent device erase_byte.
Nand flash device is with erase_byte = 0xFF, but in bio_publish_subdevice,
the sub device erase_byte will be with initial value 0.
When the image with the chunk of 0, the chunk is not written, but the
read value is 0xFF.

Most of the warnings are new, such as needing to mark fallthroughs on
cases explicitly. A few are based on signed vs unsigned comparisons.
Disable one warning that was annoying about comparing null to arguments
marked nonnull.

Ran everything through scripts/codestyle.space, which uses astyle
to generally follow K&R style.
Biggest non whitespace change is pulling brackets down on function
declarations, which I'm pretty ambivalent about, but astyle insists
on taking a stance
Extend the block i/o system to allow registered devices to advertise
an erase geometry. Devices which do not need to be explicitly erased
may skip this. Extent the Zynq spiflash code to publish the erase
geometry as read from the flash device.

Move implementation to stdio.c to sit next to the other
stdio definitions that use the debug output functions. Keep
the declaration of it, though, in printf.h to sit next to
sprintf, etc.
Don't include printf.h directly in other places, rely on stdio.h
to properly pull in these functions.

-Remove top level DEBUG=<N> define
-Rename DEBUGLEVEL to LK_DEBUGLEVEL to be clear.
-Fix the places that used DEBUGLEVEL and the few spots that #ifdef
on DEBUG.
