ARM: OMAP2+: Fix omap_device for module reload on PM runtime forbid
If a driver PM runtime is disabled via sysfs, and the module is
unloaded, PM runtime can't do anything to disable the device. Let's
let the interconnect disable the device on BUS_NOTIFY_UNBOUND_DRIVER.
Otherwise omap_device will produce and error on the following module
reload. This can be easily tested with something like:
# modprobe omap_hsmmc
# echo on > /sys/devices/platform/68000000.ocp/4809c000.mmc/power/control
# rmmod omap_hsmmc
# modprobe omap_hsmmc
