include/device/pci_ids,soc/amd/common/block/lpc: drop duplicate PCI IDs

Browse Source 
PCI_DEVICE_ID_AMD_FAM17H_LPC and PCI_DEVICE_ID_AMD_FAM17H_SMBUS redefine
the same values that are already defined by PCI_DEVICE_ID_AMD_CZ_LPC and
PCI_DEVICE_ID_AMD_CZ_SMBUS, so drop PCI_DEVICE_ID_AMD_FAM17H_LPC and
PCI_DEVICE_ID_AMD_FAM17H_SMBUS. Also add some comments to the places in
the code where the defines are used to clarify which ID is used on which
hardware generation.
