AMD hudson and yangtze boards: Let mainboard declare power button

The power button was declared by hudson's ASL as _SB.PCI0.PWRB, and
    always had the wake source declared as GPE3. This is not the correct
    wake source for all boards. On some laptops declaring a wake source is
    not needed, as the wake mechanism is handled by the EC.

Move the declaration of the power button to mainboard ASL files, and
    scope it as _SB.PWRB . This also makes the naming consistent with the
    examples in the ACPI spec. The wake source for the PWRB of HP Pavilion
    M6 1035dx is removed, as it is incorrect.
