env: common: Return specific error code on bad CRC

Callers of env_import*() functions might want to check the case when we
have incorrect environment (with bad CRC). For example, when environment
location is being defined in env_load(), call chain may look like this:

env_load() -> drv->load() = env_mmc_load() -> env_import()

Return code will be passed from env_import() all way up to env_load().
Right now both env_mmc_load() and env_import() return -EIO error code,
so env_load() can't differentiate between two cases:
1. Driver reports the error, because device is not accessible
2. Device is actually accessible, but environment is broken

Let's return -ENOMSG in env_import(), so we can distinguish two cases
mentioned above. It will make it possible to continue working with "bad
CRC" environment (like doing "env save"), instead of considering it not
functional (implemented in subsequent patch).

env: common: accept flags on reset to default env

The function set_default_env() sets the hashtable flags for import_r().
Formally set_default_env() doesn't accept flags from its callers. In
practice the caller can (un)set the H_INTERACTIVE flag, but it has to be
done using the first character of the function's string argument. Other
flags like H_FORCE can't be set by the caller.

Change the function to accept flags argument. The benefits are:
1. The caller will have to explicitly set the H_INTERACTIVE flag,
instead of un-setting it using a special char in a string.
2. Add the ability to propagate flags from the caller to himport(),
especially the H_FORCE flag from do_env_default() in nvedit.c that
currently gets ignored for "env default -a -f" commands.
3. Flags and messages will not be coupled together. A caller will be
able to set flags without passing a string and vice versa.

Please note:
The propagation of H_FORCE from do_env_default() does not introduce any
functional changes, because currently himport_r() is set to destroy the
old environment regardless if H_FORCE flag is set or not. More changes
are needed to utilize the propagation of H_FORCE.

the command is certainty user directed.

Move the H_INTERACTIVE flag from set_default_vars() to do_env_default().

cmd: nvedit: propagate envflag to set_default_vars

The env_flag in do_env_default() doesn't get propagated and therefore
gets ignored by himport_r(). This breaks to ability to "forcibly" reset
variables to their default values using the environment command.

Scenario example of the problem:
# setenv kernel uImage
# setenv .flags kernel:so
# env default -f kernel
## Error: Can't overwrite "kernel"
himport_r: can't insert "kernel=zImage" into hash table

SPDX: Convert all of our single license tags to Linux Kernel style

When U-Boot started using SPDX tags we were among the early adopters and
there weren't a lot of other examples to borrow from. So we picked the
area of the file that usually had a full license text and replaced it
with an appropriate SPDX-License-Identifier: entry. Since then, the
Linux Kernel has adopted SPDX tags and they place it as the very first
line in a file (except where shebangs are used, then it's second line)
and with slightly different comment styles than us.

In part due to community overlap, in part due to better tag visibility
and in part for other minor reasons, switch over to that style.

This commit changes all instances where we have a single declared
license in the tag as both the before and after are identical in tag
contents. There's also a few places where I found we did not have a tag
and have introduced one.

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.
