M4A785T-M: fix TOM2.
This commit is based on the commit 94fa3db366
(AMD Mahogany Fam10 ACPI table fixes.)
With commit permit to boot without pci=nocrs on the M4A785T-M board.
Before the fix dmesg contained the following:
[ 0.452071] ACPI Error: [TOM2] Namespace lookup failure, AE_NOT_FOUND
(20110112/psargs-359)
[ 0.480085] ACPI Error: [TOM2] Namespace lookup failure, AE_NOT_FOUND
(20110112/psargs-359)
[ 0.788222] ACPI Error: [TOM2] Namespace lookup failure, AE_NOT_FOUND
(20110112/psargs-359)
Now it only contains:
[ 0.312102] TOM: 0000000080000000 aka 2048M
