At present there is a confusing array of functions that handle the
device tree fix-ups needed for booting an OS. We should be able to switch
to using events to clean this up.
As a first step, create a new event type and call it from the standard
place.
Note that this event uses the ofnode interface only, since this can
support live tree which is more efficient when making lots of updates.

The current implementation of boot_relocate_fdt() places DT at the
highest usable DRAM address, which is calculated as:
env_get_bootm_low() + env_get_bootm_mapsize()
which by default becomes gd->ram_base + gd->ram_size.
Systems like i.MX53 can have multiple DRAM banks with gap between them,
e.g. have DRAM at 0x70000000-0x8fffffff and 0xb0000000-0xcfffffff , so
for them the calculated highest DRAM address is 0xafffffff, which is
exactly in the gap and thus not usable.
Fix this by iterating over all DRAM banks and tracking the remaining
amount of the total mapping size obtained from env_get_bootm_mapsize().
Limit the maximum LMB area size to each bank, to avoid using nonexistent
DRAM.

It can be useful for the OS (Linux) to know which configuration has
been chosen by U-Boot when launching a FIT image.
Store the name of the FIT configuration node used in a new string
property called 'u-boot,bootconf' in the '/chosen' node in device tree.

Quite a lot of the code in common/relates to booting and images. Before
adding more it seems like a good time to move the code into its own
directory.
Most files with 'boot' or 'image' in them are moved, except:
- autoboot.c which relates to U-Boot automatically running a script
- bootstage.c which relates to U-Boot timing
Drop the removal of boot* files from the output directory, since this
interfers with the symlinks created by tools and there does not appear
to be any such file from my brief testing.
