edac: mpc85xx fix bad page calculation
Commit b4846251727a38a7f248e41308c060995371dd05 ("edac: mpc85xx add mpc83xx support") accidentally broke how a chip select's first and last page addresses are calculated. The page addresses are being shifted too far right by PAGE_SHIFT. This results in errors such as: EDAC MPC85xx MC1: Err addr: 0x003075c0 EDAC MPC85xx MC1: PFN: 0x00000307 EDAC MPC85xx MC1: PFN out of range! EDAC MC1: INTERNAL ERROR: row out of range (4 >= 4) EDAC MC1: CE - no information available: INTERNAL ERROR The vaule of PAGE_SHIFT is already being taken into consideration during the calculation of the 'start' and 'end' variables, thus it is not necessary to account for it again when setting a chip select's first and last page address.
