OMAP: hwmod: allow omap_hwmod_late_init() caller to skip module idle in _setup()
On kernels that don't use the omap_device_enable() calls to enable
devices, leave all on-chip devices enabled in hwmod _setup().
Otherwise, accesses to those devices are likely to fail, crashing the
system. It's expected that kernels built without CONFIG_PM_RUNTIME
will be the primary use-case for this. This functionality is
controlled by adding an extra parameter to omap_hwmod_late_init().
This patch is based on the patch "OMAP: hwmod: don't auto-disable
hwmod when !CONFIG_PM_RUNTIME" by Kevin Hilman
<khilman@deeprootsystems.com>.
