Subject: [PATCH] gen_configkernel: Prepare for kernel-6.6

The microcode related config options were removed in [1] and
microcode loading is enabled when support for corresponding CPU
is enabled. Basically, this is equivalent to renaming options:

  CONFIG_MICROCODE_AMD -> CONFIG_CPU_SUP_AMD
  CONFIG_MICROCODE_INTEL -> CONFIG_CPU_SUP_INTEL

Reflect this change in gen_configkernel.sh.
