Xen support for x86/generic was added in 296772f9. This commit also
enables it for x86/64.
This was successfully tested with Xen 4.5.

This was done by simply running `make kernel_menuconfig CONFIG_TARGET=subtarget`
and then saving without changing any option.
Having consistent kernel config is important to avoid surprises, such
as the issue fixed with 6f0367c9 (where Xen support was silently
disabled when building the kernel, although it was present in the
initial config)
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.

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.

The following changes enables GPIO sysfs as well as the LEDS_GPIO option
within the kernel. This is required to enable LEDs over a GPIO
interface.

The kernel will detect if the host supports this, so we can just enable
it in the kernel config.
Tested on an APU2 with AES-NI support and a KVM VM on a Xeon E5520 host
without AES-NI support.
Throughput over an IPsec tunnel between these 2 hosts increased from
~63Mbps to ~140Mbps. Ciphers: AES_GCM_16_256/PRF_HMAC_SHA2_512/ECP_521.

Enabled Hyper-V network interface card driver, display adapter driver,
storage driver, keyboard driver, mouse driver and Hyper-V utility and
EFI boot support in the kernel for subtarget x86/64.
Convert the img file to vhd by Ubuntu qemu-img, rather than by the buildroot's

Tested on Windows Server 2008 r2 and 2012 r2 Gen1 and Gen2 VMs.

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.

The config was formed by selecting target x86/64 first, then select
CONFIG_HOTPLUG_PCI and CONFIG_HOTPLUG_PCI_ACPI with
make kernel_menuconfig CONFIG_TARGET=subtarget
The following text tries to explain how the current config was formed
1. CONFIG_PCI_LABEL and CONFIG_ATA_PIIX were removed because they were
already enabled in x86 platform config
2. CONFIG_ATA_SFF was removed because it was enabled in generic config
3. CONFIG_NLS was removed because it will be selected by CONFIG_PCI_LABEL

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.

Since r40909 openwrt can automatically shutdown when you press the
power button or try to shutdown a kvm virtual machine.
When booting a recent CC-rc2 or trunk image, it doesn't work,
as two kernel modules are missing.
Add these two kernel modules to the default packages, so users
don't need to install them manually.
