ARM: 5975/1: AT91 slow-clock suspend: don't wait when turning PLLs off
From: Julien Langer <julien.langer@gmail.com>
AT91: when turning off the PLLs during suspend, don't wait for the lock
flag to be set. Previously the code would always run into the loop
limitation of 1000 iterations because the flag is never set when turning
the PLLs off.
