Merge branch '2022-04-11-initial-valgrind-support'

To quote the author:
This series adds support for running valgrind against U-Boot's internal
malloc. This allows for much more useful reports to be generated.

Some example output of valgrind run against u-boot/master with this
branch applied may be found at [1]. Note that valgrind gives up around
acpi.  This feature still needs a lot of work on suppressions/hints to
filter out the noise properly.
