x86/microcode: Hide the config knob
In reality CONFIG_MICROCODE is enabled in any reasonable configuration when Intel or AMD support is enabled. Accommodate to reality.

config MICROCODE

- default y
+ def_bool y
depends on CPU_SUP_AMD || CPU_SUP_INTEL
- help
- If you say Y here, you will be able to update the microcode on
- Intel and AMD processors. The Intel support is for the IA32 family,
- e.g. Pentium Pro, Pentium II, Pentium III, Pentium 4, Xeon etc. The
- AMD support is for families 0x10 and later. You will obviously need
- the actual microcode binary data itself which is not shipped with
- the Linux kernel.
-
- The preferred method to load microcode from a detached initrd is described
- in Documentation/arch/x86/microcode.rst. For that you need to enable
- CONFIG_BLK_DEV_INITRD in order for the loader to be able to scan the
- initrd for microcode blobs.
-
- In addition, you can build the microcode into the kernel. For that you
- need to add the vendor-supplied microcode to the CONFIG_EXTRA_FIRMWARE
- config option.
