Investigating a hang I found having some more error information
available would be helpful, so be more verbose and also tell cam/xpt
status in case of error/panic.

While debugging a hang I noticed that in case of error in
umass_cam_attach_sim() we miss a cam_sim_free() call.
Added that to not leak resources.

mgb had a longstanding typo in function-like macro MGB_NEXT_RING_IDX's
argument, but the macro had no consumers. r365061 introduced a use of
the macro, after which mgb failed to build.

hints data. Control register 2 holds the settings a user might want to
configure, such as the timeout value for idle busses and whether to enable
the mass-writes feature.
Also add hint support for disconnecting idle busses (which was already
supported using FDT data).
Update the manpage with the new features, and also split the hints section
into separate lists of required and optional hints.
This allows privileged userspace processes to find information about the
physical page backing a given mapping. It is useful in applications
such as DPDK which perform some of their own memory management.

Further improve the drm2 deprecation message, only displaying information
about the port for relevant architectures, and skipping the message
completely from arm, which uses some parts of drm2 still.
This is mostly intended to be merged to 12, since the base bits of drm2 on
FreeBSD 13 are only really used on arm.
