OMAP2+: clock: disable autoidle on all clocks during clock init
Disable autoidle on all clocks during clock framework initialization.
(If CONFIG_PM is set, autoidle is re-enabled for all clocks later in
the boot process.)
The principle behind this patch, and some similar patches, is that the
kernel should start with all power management features disabled.
Later in the boot process, the PM code, if compiled in with CONFIG_PM,
enables or re-enables power management features.
