Subject: [PATCH 3/3] ARM: dts: Configure clock parent for pwm vibra

Commit 84badc5ec5fc ("ARM: dts: omap4: Move l4 child devices to probe
them with ti-sysc") moved some omap4 timers to probe with ti-sysc
interconnect target module. Turns out this broke pwm-omap-dmtimer
for reparenting of the timer clock.

With ti-sysc, we can now configure the clock sources in the dts with
assigned-clocks and assigned-clock-parents.

them with ti-sysc")
