Node names shouldn't have underscores. Maybe clock-controller?

OK yeah clock-controller sounds good to me.

Below is this one updated to use clock-controller naming.

I've tested that the interconnect target module enables and idles
just fine when probed with ti-sysc with PM runtime control via sys:

# echo on > $(find /sys -name control | grep \/5600)
# rwmem 0x5600fe00	# OCP Revision
0x5600fe00 = 0x40000000
# echo auto > $(find /sys -name control | grep \/5600)
# rwmem 0x5600fe10
# rwmem 0x56000024
