FROMLIST: usb: Migrate to support live DT for some driver

Use ofnode_ instead of fdt_ APIs so that the drivers can support live DT.
This patch updates usb_get_dr_mode() and usb_get_maximum_speed() to use
ofnode as parameter instead of fdt offset. And all the drivers who use
these APIs update to use live dt APIs at the same time.

UPSTREAM: usb: musb-new: omap2430: Enable DM_USB and OF support

With upcoming changes that require CONFIG_BLK, this broke
USB Mass Storage on the OMAP3 boards because if CONFIG_BLK is
enabled, it assumes that DM_USB is enabled, but it wasn't yet
available on omap3 and omap4 boards.

This patch converts the OMAP2430 MUSB glue to support DM_USB and
extracts the necessary information based on the device tree.

It's based on the ti-musb driver, but there are enough significant
differences in both the architecture and device tree entires between
am33xx and OMAP3/OMAP4, that I think it makes sense to continue to
keep the separate.

Per doc/driver-model/usb-info.txt, the USB gadget stuff hasn't
migrated to DM_USB yet, so this only supports USB Host for now.

Users wanting USB Gadgets will need to disable DM_USB and leave
it the old way for now.

treewide: replace with error() with pr_err()

U-Boot widely uses error() as a bit noisier variant of printf().

This macro causes name conflict with the following line in
include/linux/compiler-gcc.h:

# define __compiletime_error(message) __attribute__((error(message)))

This prevents us from using __compiletime_error(), and makes it
difficult to fully sync BUILD_BUG macros with Linux. (Notice
Linux's BUILD_BUG_ON_MSG is implemented by using compiletime_assert().)

Let's convert error() into now treewide-available pr_err().

Done with the help of Coccinelle, excluing tools/ directory.

The semantic patch I used is as follows:

// <smpl>
@@@@
-error
+pr_err
(...)
// </smpl>

UPSTREAM: 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.
