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.

Xen support for x86/generic was added in 1d6879ee. This commit also
enables it for x86/64.
This was successfully tested with Xen 4.5, although the serial console
is broken in the same way as x86/generic (see FS#787)

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.

This subtarget was added by 961c0eac, probably by mistake. It does
not contain anything beside a kernel config.

Do not parse /tmp/sysinfo/board_name, /proc/cpuinfo or the device tree
compatible string directly. Always use the board_name function to get
the board name.
The admswconfig package still reads /proc/cpuinfo directly. The code
looks somehow broken and the whole adm5120 which uses this package
looks unmaintained. Leave it as it is for now.

For targets using the generic board detection and board specific
settings in diag.sh, the board name is still unset at the time the
set_state() provided by diag.sh is called by 10_indicate_preinit.
Change the execution order to ensure the boardname is populated before
required the first time. Do the target specific board detection as
early as possible, directly followed by the generic one to allow a
seamless switch to the generic function for populating /tmp/sysinfo/.

x86 board.d only contains a case for the APU2, not the APU1. This
causes, for example, network configuration not to be created correctly.
Even though the APU1 seems to reaching EOL, there a still a lot of them
out there.
The APU1 and APU2 is configured in the same way and this patch should
also be considered for stable, as the error also exists there.

CONFIG_FB_EFI and CONFIG_FB_SIMPLE are needed to display console text on
EFI framebuffer.
CONFIG_FB_EFI is needed when the kernel is directly launched via EFI
shell or EFI startup.nsh script.
CONFIG_FB_SIMPLE is needed when launching the kernel via grub2 efi. In
this case, grub2 has prepared a gfxterm framebuffer and the kernel just
need to use the already prepared grub's gfxterm framebuffer to display
console text.

This change adds the sp5100_tco driver as a kernel module for the x86
target. Specifically, this can be used by the PCEngines APU2/APU3. The
reason for having this as a kernel module is to allow users to
load/unload it on demand, as the I2C interface on the APU2/APU3 will not
work while this module is loaded. More info can be found on GitHub at

watchdog: sp5100_tco: properly check for new register layouts
