Paul Walmsley 416db864c1 [ARM] OMAP3 clock: disable DPLL autoidle while waiting for DPLL to lock 
During _omap3_noncore_dpll_lock(), if a DPLL has no active downstream
clocks and DPLL autoidle is enabled, the DPLL may never lock, since it
will enter autoidle immediately.  To resolve this, disable DPLL
autoidle while locking the DPLL, and unconditionally wait for the DPLL
to lock.  This fixes some bugs where the kernel would hang when returning
from retention or return the wrong rate for the DPLL.

This patch is a collaboration with Peter de Schrijver
<peter.de-schrijver@nokia.com> and Kevin Hilman
<khilman@deeprootsystems.com>.
