481e1f23f5 x86: Add support for kernel 4.14
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.

de8370fcf2 x86: Move USB support from subtargets to target config
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.

609f169ff4 x86: Refresh subtargets kernel config
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.

1893b5622d x86: disable X2APIC support for legacy subtargets
Explicitely disable X2APIC support on legacy targets since the targeted
processor types do not support it anyway there.

Fixes FS#285.

62d0b1a444 x86/legacy: disable PAE again
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

961c0eacea x86: fix lifting kernel CPU requirements and always enable PAE
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.

4b4f739373 x86: enable 4G high memory support for generic (32bit) subtarget
This is required to fully support a number of 32bit x86 systems equipped
with more than one GB ram, e.g. certain Atom CPU machines.

d3b21bb2bb x86: enable CPU frequency scaling
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.
