Subject: [PATCH][v2] xsysace: use resource_size_t instead of unsigned long

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.
