With centralized MTU checking, there's nothing productive done by
eth_change_mtu that isn't already done in dev_set_mtu, so mark it as
deprecated and remove all usage of it in the kernel. All callers have been
audited for calls to alloc_etherdev* or ether_setup directly, which means
they all have a valid dev->min_mtu and dev->max_mtu. Now eth_change_mtu
prints out a netdev_warn about being deprecated, for the benefit of
out-of-tree drivers that might be utilizing it.
Of note, dvb_net.c actually had dev->mtu = 4096, while using
eth_change_mtu, meaning that if you ever tried changing it's mtu, you
couldn't set it above 1500 anymore. It's now getting dev->max_mtu also set
to 4096 to remedy that.

The IS_ENABLED() macro checks if a Kconfig symbol has been enabled either
built-in or as a module, use that macro instead of open coding the same.
Using the macro makes the code more readable by helping abstract away some
of the Kconfig built-in and module enable details.

Convert the memset/memcpy uses of 6 to ETH_ALEN
where appropriate.
Also convert some struct definitions and u8 array
declarations of [6] to ETH_ALEN.

Emitting netdev_alloc_skb and netdev_alloc_skb_ip_align OOM
messages is unnecessary as there is already a dump_stack
after allocation failures.
Other trivial changes around these removals:
Convert a few comparisons of pointer to 0 to !pointer.
Change flow to remove unnecessary label.
Remove now unused variable.
Hoist assignment from if.

The Apricot was a 486 PC with 4MB RAM, and an on-board ethernet
via an intel i82596 hard-wired to i/o 0x300.
Those who were using linux in the 1990's will recall that the
i82596 driver was not one of the more stable or widely used
drivers of its day. Combine that with the extremely limited
resources of the platform, and it is truly time to expire the
support for this thing.
There are some old m68k targets who were also using this chip,
so rather than poll the m68k user base, we simply cut out the
x86/Apricot support here in this commit.

Move the drivers that use the i82586/i82593/i82596 chipsets into
drivers/net/ethernet/i825xx/ and make the necessary Kconfig and
Makefile changes. There were 4 3Com drivers which were initially
moved into 3com/, which now reside in i825xx since they all used
the i82586 chip.
