Add AMD dbm690t ACPI support.
The following ACPI features are supported. 1. S1, S5 sleep and wake up (by power button or PS/2 keyboard/mouse). 2. AMD powernow-k8 driver. 3. Thermal configuration based on ADT7461. 4. IDE timing settings. 5. HPET timer. 6. Interrupt routing based on ACPI table. Signed-off-by: Joe Bao <zheng.bao@amd.com> Reviewed-by: Maggie Li <maggie.li@amd.com> Acked-by: Ronald G.
