ASRock E350M1: ACPI-related BSOD fix

On installing/starting Windows (tested with Win7 Ultimate)
the system crashes with a Blue Screen of Death, reporting an ACPI BIOS error.

From Scott Duplichan:
To avoid the Windows BSOD, the uninitialized value TOM1 in the SSDT
must be corrected. The attached patch does this. It uses the older
patching method, and not the (possibly preferred) AML generation
method. To simplify the patching operation, I moved the AML item
'TOM1' to the start of the SSDT. The patch also includes code to
confirm the AML variable TOM1 is at the expected offset before patching.

Also tested & working with Linux.
