log: Add helpers for common log levels

At present to output a log message you need something like:

log(UCLASS_SPI, LOCL_INFO, "message1");
log(UCLASS_SPI, LOCL_INFO, "message2");

but many files use the same category throughout. Also it is helpful to
shorten the length of log names, providing helpers for common logging
levels. Add some macros so that it is possible to do:

(top of file, before #includes)
#define LOG_CATEGORY UCLASS_SPI

(later in the file)
log_info("message1");
log_debug("message2");
log_err("message3");

tests: Make test_log.py tests depend on cmd_log not log

While the tests in this testcase are for the log subsystem they are only
able to be run if CONFIG_CMD_LOG is enabled as well as CONFIG_LOG, so
update the buildconfigspec requirement.

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.
