1d19bbcb68 linux/list.h: drop fallback definition of prefetch()
None of the list helpers use prefetch() anymore, and no C code relies
on getting this definition from list.h. In any case, such an arch/cpu
specific thing does not belong in a header that just consists of cpp
helper macros.

c1c2b5c6a4 linux/list.h: drop use of prefetch()
The use of prefetch() in these list helpers was dropped back in 2011
in linux (e66eed651fd1 ("list: remove prefetching from regular list
iterators")). No arch in U-Boot defines any actual prefetch(), and as
the referenced commit says, it's usually not a win anyway.

Whole-sale sync of list.h is not really feasible, but we can
synchronize the macros containing a prefetch() with their linux
implementations as of v6.15-rc5, also importing the various helpers
needed, e.g. list_is_head() and list_next_entry().

2399b628f4 list.h: synchronize hlist_for_each_entry* iterators with linux
All the way back in 2013, the linux kernel updated the four
hlist_for_each_entry* iterators to require one less auxiliary
variable:

      hlist: drop the node parameter from iterators

Currently, there is only one "user" of any of these, namely in
fs/ubifs/super.c, but that actually uses the "new-style" form, and
is (obviously, or it wouldn't have built) inside #ifndef __UBOOT__.

Before adding actual users of these, import the version as of linux
v6.1-rc1, including the hlist_entry_safe() helper used by the new
versions.

We have list_first_entry() but in some cases it is useful to find the last
item added to the list. Add a macro for this.

700a0c648d Add common (with Linux) MTD partition scheme and "mtdparts" command
Old, obsolete and duplicated code was cleaned up and replace by the
new partitioning method. There are two possible approaches now:
* define a single, static partition
* use mtdparts command line option and dynamic partitioning
Default is static partitioning.
