[for-4.17] xen/arm: domain_build: Do not use dprintk unconditionally

[Michal Orzel <michal.orzel@amd.com>]

Using dprintk results in printing additionally file name and line
number. This is something we do not want when printing regular
information unconditionally as it looks like as if there was some issue.
It also makes the logging inconsistent.

Fix this by switching to printk because this information may also be
helpful on the release builds (it would still require setting loglvl to
"info" or lower level).

Rationale for taking this patch for 4.17:
Current code results in an abnormal behavior [1] and was introduced by
the 4.17 feature (static shared memory). Even though it can only be seen
on a debug build, it should be fixed now so that we have a consistent
behavior across all the logs.
