This introduces a generic driver set for console messages routed over
inter-processor interrupt (IPI) channels. These drivers bind to a
low-level IPI driver instance for the actual transport of messages.
ipi_console_sender installs printk and/or stdout hooks to forward
messages over IPI. There is currently no buffering on the sending side.
ipi_console_receiver installs an IPI callback which stashes incoming
characters into a ring buffer, which is monitored by a nanokernel
fiber. The fiber buffers the characters on a per-line basis and sends
them to either printk or stdout. Multiple instances of this driver
may be created in case you need to receive console data from multiple
CPUs.

This buffer can be examined at runtime with a debugger to see what
is going on. Helpful if there are no other working console drivers
on the system.

This introduces the config option CONFIG_UART_CONSOLE,
and also CONFIG_CONSOLE. The UART console can finally
be disabled if desired.
The defconfigs are also being updated.

All driver Makefiles are adding the same cflags and they
have been done inconsistenly, make all drivers inherit
from the top level Makefile and remove unused includes.

Updates references to CONFIG_BSP_DIR to CONFIG_PLATFORM as part of the
BSP -> platform clean up.
Note that despite the renaming, the usage of the config option remains
unchanged.

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.

This commit fixes issues to allow build on ARM architecture.
- It fixes the include paths in Makefiles.
- It fixes the include path for the offsets.c compilation.
- It fixes the linker command. This changes is needed because gcc
ARM cross-compiler does not accept an AT() command without
specifing an address explicitly. This corner case appears
on ARM architectures when XIP is disabled.
