x86/Kconfig: Explicitly enumerate i686-class CPUs in Kconfig
The X86_P6_NOP config class leaves out many i686-class CPUs. Instead,
explicitly enumerate all these CPUs.
Using a configuration with M686 currently sets X86_MINIMUM_CPU_FAMILY=5
instead of the correct value of 6.
Booting on an i586 it will fail to generate the "This kernel
requires an i686 CPU, but only detected an i586 CPU" message and
intentional halt as expected. It will instead just silently hang
when it hits i686-specific instructions.
