The following patch adds support for the PC Engines APU2 board within
the x86_64 target. Currently this patch relies on the beep package,
which is in review at http://lists.infradead.org/pipermail/lede-
dev/2016-October/003455.html

The changes are as follows:
 - Enable the LED driver in the kernel config so it is available during boot.
Note that this driver does use DMI, so it will only load on the APU2 board.
 - Enable DEVMEM within the kernel config for use with the flashrom package.
 - Add userspace support for LEDs & reset button, as well as the default
network config.
