Commit bc8e80d56c1ec ("x86/mce: Merge mce_amd_inj into mce-inject")
removed the last .c file from arch/x86/ras/, so that there is now
only a lonely Kconfig file in this folder. Its config switches
CONFIG_RAS_CEC and CONFIG_RAS_CEC_DEBUG are only used in code that
resides in drivers/ras/, so those Kconfig switches should better
reside in drivers/ras/, too. Thus move the contents of arch/x86/ras/
into drivers/ras/Kconfig now.
