[U-Boot] u-boot-x86 sf probe fail

[Yaroslav]

Hello.

I have a similar problem with U-Boot on Intel Atom C2000.
And I have found that the issue with the SPI flash is caused by a file
x86/cpu/coreboot/pci.c which contains an empty driver claiming to be
compatible with intel,pch7 and intel,pch9. After commenting it out the SPI
flash is being probed and works just fine.
Maybe the file contains outdated code or something. U-boot maintainers
should check it.
