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.

BUILD_BUG_* macros have been defined in several headers. It would
be nice to collect them in include/linux/bug.h like Linux.
This commit is cherry-picking useful macros from include/linux/bug.h
of Linux 4.4.
I did not import BUILD_BUG_ON_MSG() because it would not work if it
is used with include/common.h in U-Boot. I'd like to postpone it
until the root cause (the "error()" macro in include/common.h causes
the name conflict with "__attribute__((error()))") is fixed.

add missing definitions for the ubi/ubifs sync
with linux 4.2, also change "#define kfree ..."
into a static inline, so prevent ubi compile error:
CC drivers/mtd/ubi/fastmap.o
drivers/mtd/ubi/fastmap.c: In function 'scan_pool':
drivers/mtd/ubi/fastmap.c:475:3: error: called object 'free' is not a function

Added a header file to include various linux specific APIs like
pr_debug, WARN_ WARN_ON_ONCE etc.. in order to avoid compilation
error while building dwc3 driver.
