So far we had a menu that allowed multi-images only on a per-SoC basis.
This patch drop this, so we can use the newly added sama5d2 and sama5d3
support in the same image. The sama5d2 support is not yet complete, but
it boots to shell and network and QSPI-NOR drivers are already
available.

Since ed04a7c3 ("pbl multiimage: Allow to check image sizes"), we can
now check sizes per entry point, so no need to a Kconfig symbol that
applies to all boards for that. Thus drop the Kconfig symbol for
multi-image, so per-entry-point max image sizes can follow in future.

Add hardware description, chip identification and clock changes to

This increases the size of my LZO-compressed THUMB2 barebox by 843 bytes.

There's no need to use %c for ESC, when we can use the appropriate
escape sequence directly. Do this and shave off 60~ bytes on my
compressed THUMB-2 barebox.

When quirk->init is NULL, we evaluate an uninitialized rc.
Is we have already checked for rc < 0 at the point of assignment,
this if clause isn't needed. Remove it.

We currently create all boot entries before attempting boot. This is
less than optimal, because this may involve probing devices that won't
be used for actual boot.
In preparation for changing this, refactor the code, so we only have one
loop we need to touch.

m skipping an

The SDMMC2 doesn't need any special setup for High-Speed modes, except
for the clock changes. Thus set the cap flags if the max clock would
allow for the higher speed mode.

The NULL assignment is a left over from when it was a global variable.
am_usbphy is local now and is just going out of scope, so need to NULL
it.

The dummy read was a left over from an abandoned merge with the existing
support for the SoCFPGA variant of the Designware MAC. It doesn't exist
in either the U-Boot or kernel drivers for the EQOS, thus drop it.
