This adds initial support for kernel 4.19 to the x86 target.
The patches and the kernel configurations were copied from kernel 4.14
and then refreshed.
The legacy and the genode target will not support PAE any more because
they use a CPU type which does not support PAE, the generic sub target
still supports PAE.

This refreshes the kernel configuration for kernel 4.14.
First this was run for the legacy target:
make kernel_oldconfig
Then for all targets including the legacy target this was run:
make kernel_oldconfig CONFIG_TARGET=subtarget
The option CONFIG_104_QUAD_8 was added to the generic configuration
because it would have been automatically removed.

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.

Compaction is the only memory management component to form high order (larger
physically contiguous) memory blocks reliably. The page allocator relies on
compaction heavily and the lack of the feature can lead to unexpected OOM
killer invocations for high order memory requests. You shouldn't disable this
option unless there really is a strong reason for it.

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.

The subtarget configuration was refresh with kernel 4.14 and the
options needed to make it compile on kernel 4.9 were added manually.

Cover temperature sensors for all mainstream 64-bit processors, including
AMD 10h and 15h families, Intel iCore, Xeon, Atom, and Via Nano. Also
add CPUID support for user-space applications to detect CPU type.
Include the on-chip sensors for 64-bit CPU's in the generic profile

The Xen serial console has been broken since the xen_domu subtarget
was merged in the generic x86 subtarget (commits 1d6879ee and 371b382a).
The reason for the broken serial console seems to be an IRQ conflict
between the serial console driver and the PATA_LEGACY driver:
[ 1.330125] genirq: Flags mismatch irq 8. 00000000 (hvc_console) vs. 00000000 (platform[pata_legacy.4])
[ 1.330134] hvc_open: request_irq failed with rc -16.
[ 1.330148] Warning: unable to open an initial console.
Just drop the PATA_LEGACY driver from the x86/generic and x86_64
subtargets, since this driver is marked experimental and only supports
very old ISA devices anyway. It is still included in the x86/legacy
subtarget where it rightfully belongs.

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.

PATA support has been removed from x86-generic without any note in LEDE
r538. Not including them makes the generated images incompatible with older
(and some newer) hardware without any significant gain.
Add it back, and also add the same drivers (as far as available) to x86-64.

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
