First check the presence of the ipu firmware in the boot partition. If present enable the ipu and the related clocks & then move on to load the firmware and eventually start remoteproc IPU1/IPU2.
do_enable_clocks by default puts the clock domains into auto which does not work well with reset. Hence adding do_enable_ipu_clocks function.
