[PATCH] arch: m68k: remove incomplete, unusable Apollo hardware support

[Ethan Nelson-Moore <enelsonmoore@gmail.com>]

The m68k architecture contains very incomplete support for running on
Apollo Domain hardware. There are only timer, console, and framebuffer
drivers, and no storage or network drivers, so there is no way to
practically use it. It is not even capable of rebooting by itself (see
dn_dummy_reset() in arch/m68k/apollo/config.c).

arch/m68k/apollo has only received tree-wide changes and fixes by
inspection in the entire Git history (since Linux 2.6.12-rc2), so there
is clearly no interest in completing support for Apollo hardware.
Remove it to reduce future maintenance workload.

There are no uses of the removed <asm/bootinfo-apollo.h> UAPI header or
the constants removed from the <asm/bootinfo.h> UAPI header on GitHub
or Debian Code Search.
