[PATCH] fdt: Make fdt addr -q quieter

From: Peter Hoyes <Peter.Hoyes at arm.com>

64597346 "fdt: Add -q option to fdt addr for distro_bootcmd" introduced
the -q option for fdt addr, which sets the current working fdt address
without printing any output.

baf41410 "fdt: Show a message when the working FDT changes" made the
utility function set_working_fdt_addr (in cmd/fdt.c) output a message
on each invocation, even if called via fdt addr -q, in which case its
output is now slightly noisier.

To fix this, move the printf outside of set_working_fdt_addr to three
call sites:
 * bootm_find_images (the use case for which the additional output was
   added in baf41410).
 * fdt addr, but only if the 'quiet' argument is not set.
 * fdt move.

This also has the advantage of printing the specified address instead of
the translated address when using the sandbox.

Remove assertions from the fdt addr test case when:
 * Calling set_working_fdt_addr directly.
 * Calling fdt addr with the -q argument.
