src/soc/intel/denverton_ns: Use improvement in coreboot since 4.9
- enable microcode in cbfs (won't boot without microcode)
- force num fit entry to 1 to avoid crash in cbfstool/fit.c
- re-enable FSP-CAR (tested to boot, while I couldn't boot with NEM)
- enable io driver for uart in legacy mode (ie emulating legacy port by
configuring the pci to legacy io address and hiding the pci device)
