Commit 4f144a41 "malloc: work around some memalign fragmentation
issues" enhanced memalign() so that it can succeed in more cases where
heap fragmentation is present. However, it did not solve as many cases
as it could. This patch enhances the code to cover more cases.

The alignment code works by allocating more space than the user requests,
then adjusting the returned pointer to achieve alignment. In general, one
must allocate "alignment" bytes more than the user requested in order to
guarantee that alignment is possible. This is what the original code does.
The previous enhancement attempted a second allocation if the padded
allocation failed, and succeeded if that allocation just happened to be
aligned; a fluke that happened often in practice. There are still cases
where this could fail, yet where it is still possible to honor the user's
allocation request. In particular, if the heap contains a free region that
is large enough for the user's request, and for leading padding to ensure
alignment, but has no or little space for any trailing padding. In this
case, we can make a third(!) allocation attempt after calculating exactly
the size of the leading padding required to achieve alignment, which is
the minimal over-allocation needed for the overall memalign() operation to
succeed if the third and second allocations end up at the same location.

This patch isn't checkpatch-clean, since it conforms to the existing
coding style in dlmalloc.c, which is different to the rest of U-Boot.

We always build for a mips32 or higher ISA, so this ".set mips32"
directive is redundant. Once MIPSr6 support is added it will become
harmful since some instruction encodings change & this directive will
cause the older encodings to be incorrectly emitted instead of the
appropriate ones for the build.

In preparation for supporting MIPSr6, remove this redundant directive.

Add support for targetting MIPS32r6 & MIPS64r6 systems, in the same way
that we currently select release 1 or release 2 targets. MIPSr6 is not
entirely backwards compatible with earlier releases of the architecture.
Some instructions are encoded differently, some are removed, some are
reused, so it is not practical to run U-Boot built for earlier revisions
on a MIPSr6 system. Update their Kconfig help text to reflect that.
