This makes it possible to use different sub target configurations for
kernel 4.19 for example.
To support kernel 4.9 and kernel 4.14 with the same configuration file
already needed some extra work this will not be needed for kernel 4.19
any more.

While working on a new target (meson), the kernel build failed due to
missing DRM_DEBUG_MM_SELFTEST symbol. This can potentially happen on all
targets that enable DRM drivers in the kernel config or via kmod
packages, so add it to the generic config and remove it from x86
subtarget configs, together with DRM_DEBUG_MM.

This adds basic support for kernel 4.14, this was tested in qemu only.
The subtarget configuration was refresh with kernel 4.14 and the
options needed to make it compile on kernel 4.9 were added manually.

All x86 subtargets enable USB support, so it makes sense to enable it
in the target config instead, to avoid duplication.
Also refresh subtarget configs accordingly.

This was done by simply running `make kernel_menuconfig CONFIG_TARGET=subtarget`
and then saving without changing any option.
Most of the removed options can be explained because they are already
present in the target config or in the generic 4.9 config:
- PAE-related options, enabled by default on x86 by 961c0eac
- LZO-related options, enabled by default since 4.9
As far as I understand the build system, this shouldn't have any
user-visible impact, because the build system already merges the
various kernel configs during build.

Explicitely disable X2APIC support on legacy targets since the targeted
processor types do not support it anyway there.
Fixes FS#285.

commit 961c0eacea ('x86: fix lifting kernel CPU requirements and always
enable PAE') broke some older geode boards such as Soekris net4826.
Hence disable PAE on x86/legacy again in order to still support those
very old non-PAE capable CPUs.
Fixes FS#773 - PAE broke Soekris net4826

commit 89878f60f4 x86: lift kernel minimum CPU requirement to Pentium MMX
caused kconfig havoc. Fix this and make sure PAE is enabled even on legacy
CPUs as the minimum required CPU has been Pentium MMX for a while now and
hence PAE is supported even on the x86_legacy target.

CPU frequency scaling enables the operating system to scale the CPU
frequency up or down in order to save power. CPU frequencies can be
scaled automatically depending on the system load, in response to ACPI
events, or manually by userspace programs.
