Use resource_size_t for physical address of SystemACE
chip. This fixes the driver brokeness for 32 bit systems
with 64 bit resources (e.g. PPC440SPe).

Also this patch adds one more compatible string for more
clean description of the hardware, and fixes a sector_t-
related compilation warning.

Hey Yuri,

I actually already picked up the last version of your patch after
fixing it up myself.  It's currently sitting in Paul's powerpc tree
and it will be merged into mainline when Linus gets back from
vacation.

Can you please spin a new version with just the addition of the
compatible value and base it on Paul's tree.

Thanks,
g.

 Oops. Indeed. Thanks.

 Sure. I've generated the patch against the origin/merge branch of Paul's 
tree, and posting it as separate "[PATCH] xsysace: add compatible string
".
