Memo to self: xconfig is a can of worms, try to avoid working on it.

The current configuration mini-language (CML1) has lots of hidden
restrictions.  One of them is that you cannot reliably select a
variable in two different menus.  arch/ia64/config.in is breaking this
rule in several places, some of which work, others do not.  This patch -

* Indents arch/ia64/config.in so I can see what is dependent on HP_SIM.
  The bulk of the patch is indent changes, if this is a problem I can
  do another patch without the indent changes, but the result is much
  less readable.

* Moves force setting of DEVFS for SN[12] to fs/Config.in.

* Removes dependency on CONFIG_DRM_AGP.  That variable does not exist
  and breaks xconfig for ia64.  This is a generic 2.4.18/2.4.19-rc bug
  and has been sent to Marcelo.

* Removes the attempt to set BLOCK variables from arch/ia64/config.in
  and adds the dependency on HP_SIM to drivers/block/Config.in.  This
  is the only method that stands any chance of working for xconfig.
  ACPI is already done this way for the same reason, the arch
  dependencies are inside the ACPI menu, not in the arch menu.

* Moves force settings of ACPI variables based on HP_SIM to _after_
  HP_SIM is actually defined.  General config bug, not xconfig specific.
