[patch] edac i5000: fix pointer math in i5000_get_mc_regs()

"pvt->ambase" is a u64 datatype. The intent here is to fill the first
half in the first call to pci_read_config_dword() and the other half in
the second. Unfortunately the pointer math is wrong so we set the wrong
data.

I don't have the hardware to test this. Please review carefully.
