mtd: spi-nor: Create an indirection on the part name

We currently print through sysfs and debugfs the name of the part if the
.name field, which is legacy, has been filled in the ID table (otherwise
"(null)" is printed). These IDs had an interest until manufacturers
started re-using more and more extensively the so called unique JEDEC
IDs. At this stage, a name that was tailored for a chip sold in 2016 may
no longer be relevant for a chip sold in 2026. Still showing this name
through the various filesystems may confuse people, removing these names
cannot be done since they are now part of the user ABI (because of
sysfs).

In order to allow overwriting the .name field (which is part of a
read-only structure), let's create a spi-nor pointer which will by
default point to that .name, but which can be cleared in fixup hooks to
make sure the name is hidden on newer parts.
