Linux defines them in <linux/device.h>.

printk: collect printk stuff into <linux/printk.h> with loglevel support
When we import code from Linux, with regular re-sync planned, we want
to use printk() and pr_*(). U-Boot does not support them in a clean
way. So, people end up with local macros, or compat headers here and
there, then we occasionally see build errors of definition conflicts.
We have include/linux/compat.h, but putting all sorts of unrelated
things into a single header is just a temporal workaround. Hence this
patch, to find the best home for all printk variants. If you want to
use printk() and friends, please include <linux/printk.h>. This header
is self-contained, and pulls in only a few headers.
When I was testing this clean-up, I noticed the image size exceeded
its platform limit on some boards. This is because all pr_*() that
were previously defined as no-op in include/linux/mtd/mtd.h (unless
CONFIG_MTD_DEBUG is set), are now enabled.
To make such boards happy, this commit also implements CONFIG_LOGLEVEL.
The concept is similar to the kernel parameter "loglevel". (Actually,
the Kconfig help message was taken from kernel-paremeter.txt of Linux)
Messages with a loglevel smaller than console loglevel will be printed.
The difference is the loglevel is build-time determined. To save the
image size, lower priority pr_*() are compiled out. I set the default
of CONFIG_LOGLEVEL to 6, i.e. pr_notice and higher priority messages
are compiled in.
I adjusted CONFIG_LOGLEVEL to avoid build error for some boards.

Provide a generic io.h & address mapping functions
Most architectures currently supported by U-Boot use trivial
implementations of map_to_physmem & virt_to_phys which simply cast a
physical address to a pointer for use a virtual address & vice-versa.
This results in a lot of duplicate implementations of these mapping
functions.
The set of functions provided by different architectures also differs,
with some having implementations of phys_to_virt & others not. A later
patch will make use of phys_to_virt in architecture-neutral code, and so
requires that it be provided for all architectures.
This patch introduces an asm-generic/io.h which provides generic
implementations of address mapping functions, allowing the duplication
of them between architectures to be removed. Once architectures are
converted to make use of this generic header it will also ensure that
all of phys_to_virt, virt_to_phys, map_physmem & unmap_physmem are
provided. The 2 families of functions differ in that map_physmem may
create dynamic mappings whilst phys_to_virt may not & therefore is more
limited in scope but doesn't require information such as a length &
flags.
This patch doesn't convert any architectures to make use of this generic
header - later patches in the series will do so.

This adds the proper implementation for the BTRFS filesystem.
The implementation currently supports only read-only mode and

include: Add a variadic macro to call a callback for all arguments
Add a header variadic-macro.h which defines the CALL_MACRO_FOR_EACH marco.
This macro can be used as follows:
#define TEST(x)
CALL_MACRO_FOR_EACH(TEST, a, b, c, d)
This will expand to
TEST(a) TEST(b) TEST(c) TEST(d)
The nice thing is that CALL_MACRO_FOR_EACH is a variadic macro, thus the
number of arguments can vary (although it has an upper limit - in this
implementation 32 arguments).
