Booting a beaglebone black from eMMC is broken since:

    ARM: AM335x: Beaglebone: Use stripped down devicetree for MLO

The stripped down device tree does not have the eMMC device node which
the beaglebone black needs for booting. Add this node to the common dts
file, but keep it disabled. It gets enabled later with a call to
am33xx_of_register_bootdevice() when the system is booted from eMMC.

Commit 0d6392d introduced a stripped
down device tree used for both white and black Beaglebone variants
that included the 256 MiB memory node from am335x-bone-common.dtsi.
This leads to the following error in the MLO:

    mmu: Critical Error: Can't request SDRAM region for ttb at 9fff4000

This patch removes the (for the Beaglebone black) invalid memory size
from the common device tree and instead registers the memory bank
manually in the board file.

As the place for the atags now is determined automatically the call
from the boards can be removed.

am33xx_register_ethaddr must be called before cpsw driver start.
Move it from devices_initcall to coredevice_initcall.

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().

The bootsource functions are not specific to the first stage
bootloader. They may also be used for detecting the
bootsource to decide where to load the environment from.

Also clean up includes in board files.

The muxing in the am33xx_mux.c file is not generic as the muxing
setup does not fit for every board. Move the structs and functions
to the mach/am33xx-mux.h so board dependend mux setups can be
created.

environment.h is for environment variables, not for the environment
