[PATCH] kbuild : Make Fusion MPT selectable from "Device drivers" menu

["Robert P. J. Day" <rpjday@mindspring.com>]

  Rewrite the Fusion MPT Kconfig file so that all of MPT functionality
is entirely selectable from "Device drivers."

Signed-off-by: Robert P. J. Day <rpjday@mindspring.com>

  The original Kconfig file seems to have an odd structure, as you can
see from the first part of the file:

========================================================
menu "Fusion MPT device support"

config FUSION
        bool
        default n

config FUSION_SPI
        tristate "Fusion MPT ScsiHost drivers for SPI"
        depends on PCI && SCSI
        select FUSION
        select SCSI_SPI_ATTRS
        ...
========================================================

  note how the majority of entries in that file don't directly
*depend* on FUSION.  instead, they depend on *external* config
variables, and *select* FUSION, and this is not the only place i've
noticed that kind of dependency wording.

  is that a regular feature?  having that structure certainly makes it
slightly more difficult to rewrite the menu entries, and it's not
clear there's any obvious advantage to doing it that way.
