intel/*/acpi: Increase range length of MCHBAR buffer to 32 kB
Linux kernel 2.6.31 reports the warning below on Intel Ivy Bridge (with
FSP).
resource map sanity check conflict: 0xfed10000 0xfed17fff 0xfed10000 0xfed13fff pnp 00:01
Since Sandy Bridge the length of the MCHBAR is 32 kB and it is already
used that way in other places.
$ more src/northbridge/intel/fsp_sandybridge/acpi/hostbridge.asl
[…]
OperationRegion (MCHB, SystemMemory, DEFAULT_MCHBAR, 0x8000)
[…]
So instead of 16 kB specify that 32 kB are decoded in that memory
range for Intel Sandy Bridge, Ivy Bridge and Haswell.
(Linux kernel 3.10 does not warn about that.)
