x86/ras: Move contents from arch/x86/ras/Kconfig into drivers/ras/Kconfig

Browse Source 
Commit

  bc8e80d56c ("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.

config RAS_CEC
bool "Correctable Errors Collector"
depends on X86_MCE && MEMORY_FAILURE && DEBUG_FS
help
This is a small cache which collects correctable memory errors per 4K
page PFN and counts their repeated occurrence. Once the counter for a
PFN overflows, we try to soft-offline that page as we take it to mean
that it has reached a relatively high error count and would probably
be best if we don't use it anymore.
Bear in mind that this is absolutely useless if your platform doesn't
have ECC DIMMs and doesn't have DRAM ECC checking enabled in the BIOS.
config RAS_CEC_DEBUG

depends on RAS_CEC
help
Add extra files to (debugfs)/ras/cec to test the correctable error
collector feature. "pfn" is a writable file that allows user to
simulate an error in a particular page frame. "array" is a read-only
file that dumps out the current state of all pages logged so far.
