Pull IDE updates from David Miller:

 1) Fix mem region name in tx4949ide driver, from Christophe JAILLET.

 2) Make drive->dn read only, it should not be changeable by users. From
    Dan Carpenter.

 3) Several cast fixups from Krzysztof Kozlowski.

There is also going to be a removal of a now unused IDE driver, but that
will come via the MIPS tree.
