This adds the following patches to the x86 target:
sp5100_tco: Add AMD Mullins platform support
sp5100_tco: Add AMD Carrizo platform support
sp5100_tco: fix the device check for SB800 and later chipsets
watchdog: sp5100_tco: properly check for new register layouts
With these added, the sp5100_tco driver can then be used on newer AMD
platforms, such as the PCEngines APU2/APU3 boards.
