soc/amd/common/block/lpc/lpc: drop custom lpc_set_resources
Drop the custom lpc_set_resources implementation that does some register
access that has no effect and then calls pci_dev_set_resources and use
pci_dev_set_resources for set_resources in amd_lpc_ops instead.
The SPI controller's base address got configured early in boot in the
lpc_set_spibase call and the enable bits got set early in boot in the
lpc_enable_spi_rom call.
TEST=The contents of the SPI_BASE_ADDRESS_REGISTER at the beginning and
at the end of the call stay the same, so it's simply a no-op.
