[PATCH] EDAC, pnd2: Fix ioremap() size in dnv_rd_reg() from 64K -> 32K

[Stephen Douthit]

BIOS has marked the 32K MCHBAR window as reserved, so when dnv_rd_reg()
tries to ioremap() a 64KB region you get warnings like:

resource sanity check: requesting [mem 0xfed10000-0xfed1ffff], which spans more than reserved [mem 0xfed10000-0xfed17fff]
caller dnv_rd_reg+0xc8/0x240 [pnd2_edac] mapping multiple BARs

ioremap() the correct size on Denverton platforms to get rid of those
warnings.
