Subject: [PATCH] x86, microcode: Correct kconfig dependencies

From: Borislav Petkov <bp@...e.de>

I have a randconfig here which has enabled only

 CONFIG_MICROCODE=y
 CONFIG_MICROCODE_OLD_INTERFACE=y

with both

 # CONFIG_MICROCODE_INTEL is not set
 # CONFIG_MICROCODE_AMD is not set

off. Which makes building the microcode functionality a little
pointless. Don't do that in such cases then.
