AMD Fam15tn: Split DSDT into common sections
Split the Parmer, Family 15tn, and Hudson DSDT into groups. This splits
the DSDT table into includable ASL files which carry details specific
to the Family 15tn APU, the Parmer platform, and the Hudson FCH. The
dsdt.asl file in the mainboard directory contains only #include
references to the appropriate files.
Initially, this split was done by moving each piece of functionality
into its own file (e.g. IRQ routing and mapping, processor tree, sleep
states and sleep methods, etc.) and those pieces were #included in
dsdt.asl to ensure an exact match (via acpidump/acpixtract/iasl -d)
with the extant version of the table. Once the new tables were found
to exactly match the existing tables, the pieces were rearranged into
reasonable groups (e.g. fch.asl, northbridge.asl, pci_int.asl, etc.).
Some include files have no content but are left as a template for
other platforms and as placeholders for completing the ACPI
implementation for Parmer (e.g. thermal.asl, superio.asl, ide.asl,
sata.asl, etc.).
