The Xen serial console has been broken since the xen_domu subtarget
was merged in the generic x86 subtarget (commits 296772f9 and b36e24f3).
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.

This is a backport of 641a65fd06 in master.
This change re-enables PAE for the 32-bit x86 subtarget, which is
interesting in its own right but also necessary for Xen support.
Commit af1d1ebd ("x86: enable 4G high memory support for generic (32bit)
subtarget") inadvertently disabled both PAE and Xen support.

MMC support has been added to x86-64 a while ago, there is no reason not
to support it in x86-generic as well.

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
events, or manually by userspace programs.

Enable support for DMI decoding in the kernel so that we can access
manufacturer and model information via sysfs.
Also remove redundant per-subtarget DMI overrides and preset a few
previously unset symbols popping up due to the now enabled DMI support.

copied target/linux/x86/config-3.14 and target/linux/x86/patches-3.14 to
3.18 equivalents and then tweaked until it built.
Tested on alix2, soekris net4826 and soekris net4521.
Still having trouble with net4826 booting from Grub, alix2 and net4521
are fine.

The pata-cs5535/pata-cs5536 driver is actually fairly rare: it only gets used on embedded platforms. Therefore, we remove it from the generic x86 configuration.
Also, add definitions for other useful geode modules (high-res timers, MFGPT timers, etc).

This patch brings up the net5501 platform.
Note that the x86/ target included support for all x86/ class
processors. That's not technically correct. This should be constrained
only to the "generic" subtarget. Every x86-class target that isn't
generic should be able to select only the optimizations/capabilities
applicable to that architectural variant.
It's also assumed that all x86 processors have keyboard & mouse ports,
ISA, DMI, ACPI... the embedded ones typically don't. Again, moving
that to the generic subtarget.
Fortunately, this was a fairly benign tweak.
The net5501 board includes the following logic:
Geode/LX processor
CS5535 super-I/O chip
PC87360 sensor chip
Via Rhine Ethernet controllers
Via Sata controllers
USB, LEDS, I2C
