treewide: replace with error() with pr_err()

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

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>

We are now using an env_ prefix for environment functions. Rename these
two functions for consistency. Also add function comments in common.h.

Quite a few places use getenv() in a condition context, provoking a
warning from checkpatch. These are fixed up in this patch also.

exynos5: Don't potentially undervoltage the CPU

For snow when chainloading u-boot the CPU seems to be running at full
speed. The lower CPU voltage seems to be ok for u-boot, but when booting
linux (bringing up all cores) I'm seeing random crashes.

Bump the voltage up to a level that's safe for all cpu frequencies.

exynos5-dt-types: add board detection for Odroid XU3/XU3L/XU4.

This commit adds additional file with implementation of board
detection code for Odroid-XU3/XU4.

The detection depends on compatible found in fdt:
- "samsung,exynos5" - uses Exynos5 generic code
- "samsung,odroidxu3" - try detect XU3 revision

There are few revisions of Odroid XU3/XU4, each can be detected
by checking the value of channel 9 of built-in ADC:
Rev ADC Board
0.1 0 XU3 0.1
0.2 372 XU3 0.2 | XU3L - no DISPLAYPORT
0.3 1280 XU4 0.1

The detection code depends on the ADC+10% value.

Implementation of functions:
- set_board_type() - read ADC and set type
- get_board_rev() - returns board revision: 1..3
- get_board_type() - returns board type string

Additional functions with return values of bool:
- board_is_generic() - true if found compatible "samsung,exynos5"
but not "samsung,odroidxu3"
- board_is_odroidxu3() - true if found compatible "samsung,odroidxu3"
and one of XU3 revision.
- board_is_odroidxu4() - true if found compatible "samsung,odroidxu3"
and XU4 revision.

After I2C controller init, the get_board_type() can check
if the XU3 board is a "Lite" variant, by probing chip
0x40 on I2C0 (INA231 - exists only on non-lite).
This is useful for setting fdt file name at misc_init_r().

Enabled configs:
- CONFIG_ENV_VARS_UBOOT_RUNTIME_CONFIG
- CONFIG_ODROID_REV_AIN
- CONFIG_REVISION_TAG
- CONFIG_BOARD_TYPES

Some boards use device tree for almost all board-specific configuration.
They therefore do not need their own separate board code, but can all use
the same version. Add a common version of the board code. It uses the
PMIC, regulator and video bridge uclasses. This will support smdk5250,
smdk5420, snow, spring, pit and pi.
