With multiboard support the compiletime generated BOARDINFO string
gets more and more meaningless. This removes it from Kconfig and
replaces it with a variable that can be set at boardlevel.

Also many boards have a standard setting for the hostname in the
environment. This patch also moves the standard to C code by calling
barebox_set_hostname().

Add support for the GK802 'QUAD CORE Mini PC', which seems to be loosely
based on the Freescale i.MX6Q HDMI dongle reference design.
It is supposedly identical to the Hiapad Hi802.
