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 bootrom only reads an image if the correct checksum is present in the
header. The calculation is pretty simple:
sum over all words from 0x20 to 0x44
Two of this words are the image length. That is why the checksum can not be
calculated until barebox_image_size is known.
The easiest solution is a program that has to be run after make.

On some i.MX SoCs the SDRAM controller has chipselect 2 enabled
by reset default. This confuses our SDRAM size detection. We
already have a fix for this in place. This patch adds the fix
for i.MX35 which needs it aswell. Also since we now detect the
SDRAM size in the SoC specific entry functions we have to apply
the fixup there, too.

This allows us to better detect whether a clk is enabled or not.
- If we can ask a clk, ask it. If it's enabled, go on and ask parents
- If we can't ask it, but it can be enabled, depend on the enable_count.
if it's positive, go on and ask parents
- If we can't ask it and it cannot be enabled, assume it is enabled
and ask parents.
This makes the CLK_ALWAYS_ENABLED unnecessary, since the fixed clk now
always returns 1 in its is_enabled callback.
