Subject: [PATCH 5.12 335/700] EDAC/igen6: fix core dependency

From: Randy Dunlap <rdunlap@...radead.org>

[ Upstream commit 0a9ece9ba154dd6205709108180952c55e630833 ]

igen6_edac needs mce_register()/unregister() functions,
so it should depend on X86_MCE (or X86_MCE_INTEL).

That change prevents these build errors:

ld: drivers/edac/igen6_edac.o: in function `igen6_remove':
igen6_edac.c:(.text+0x494): undefined reference to `mce_unregister_decode_chain'
ld: drivers/edac/igen6_edac.o: in function `igen6_probe':
igen6_edac.c:(.text+0xf5b): undefined reference to `mce_register_decode_chain'
