omap_save_bootinfo derefences the argument passed to barebox without

somewhere in SRAM and is word aligned. This at least makes sure that

since the SRAM addresses/sizes differ between SoCs.

The macb/gem core is used by the Zynq SoC. In preparation of sharing
the macb driver between at91 and Zynq, rename the platform data to
'struct macb_platform_data', and move the definition to a common
location.

Rename the barebox_loc environment variable to bootsource, since
- barebox_loc is a mixture between abbriviation and fulltext which is not nice
- technically it describes the source the SoC has booted from. This is not
necessarily barebox but could also be some other first stage loader.

The second UART is used on the mba53 baseboard. The first UART is only
used on custom hardware. This patch changes the UART to the one used
on the freely available baseboard.

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 Avnet ZedBoard is an evalboard with a Zynq-7020 based MPSoC.
There is also a Digilent ZedBoard, that is the same but only for
academic customers.

The pcm051 has no MMC WP pin. This pin is used for a gpio and
needs to be muxed different. Created a custom mux file for
this case.

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.
