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.
