[PATCH] ARM: Orion5x: ts78xx: Add IOMEM for virtual addresses.

[Andrew Lunn]

Also convert logical or to + for register offsets from base
addresses. This fixes a number of warnings currently seen in
linux-next:

warning: passing argument 2 of '__raw_writeb' makes pointer from
interger without cast.

I had prepared an identical patch but not posted it, so I now
applied your version on top of the iomem cleanup branch that
has all the other changes like this one.
