ARM: i.MX8M: implement bootrom log viewing command
The ROM event log[1] of the i.MX8M* can help with debugging boot
failures as it lists various information about boot mode, image,
fallback and recovery as well as timestamps when some actions along
the boot process occurred.
Add a new bootrom -l command that supports reading this out. A generic
name is intentionally chosen, as other SoCs also provide similar
functionality and it would be nice if they can just reuse the name and
command line arguments in future.
