ARM: dts: dra7: Fix functional clocks for DMTimer devices

The hwmod and clkctrl integration code is currently assigning the
clkctrl clock associated with MODULEMODE as the main functional
clock for nodes that have the ti,hwmods property. This is wrong
for devices that actually use mux or gate clocks as their main
clock and that are not yet converted to the ti-sysc node hierarchy.

The dmtimer clocksource driver cannot use this clock to configure
its parents. The dmtimer consumers got lucky so far due to the
default clock matching the requested parent clock, and a silent
successful return in the omap_dm_timer_set_source() function. Fix
this by adding the actual mux clocks to the DMTimer nodes with
the "fck" clock-name. These clocks are expected to remain even
after the nodes have moved under a ti,sysc parent node.
