Unconditionally enable the clocks for all imx6 devices that we have drivers
for, or that are required to run the chip (such as busses).  Turn off all
the devices we don't yet have drivers for.

Some day we will have a fully functional imx6 clock driver so that we can
manage clocks based on fdt data.  This will have to do until then.
Add VirtIO console driver

Support for the multiport feature is mostly implemented, but currently
disabled due to some potential races in the hot plug code paths.

Port t_pipe2.c to FreeBSD

- Omit the pipe2_nosigpipe testcase on FreeBSD (FreeBSD doesn't have
  O_NOSIGPIPE).
- Convert "fcntl(n, F_CLOSEM)" to "closefrom(n)".
- Save and restore the resource limit on the number of files (RLIMIT_NOFILE).

- Mark unused parameters __unused in handler

be valid on NetBSD

Use <atf_srcdir>/truncate_test.root_owned instead of /usr/bin/fpr as fpr does
not exist on FreeBSD

truncate_test.root_owned will be generated at build time and owned by root
