The only remaining user of board_time_init() is the of-generic
machine, and that just calls the global timer_init() function.
Calling that one has no effect on non-DT platforms, so we can
simply call it unconditionally in place of board_time_init().

Hmm, I fixed it locally, but Baolin forwarded the version from the
original submission that had the same bug (timer_init instead of timer_probe):

https://www.spinics.net/lists/linux-sh/msg52798.html

I'll just send the correct version once more.

I am sorry I missed your fixes, but thanks to resend them to remove
the last user of the obsolete read_persistent_clock().
