Tony Lindgren a5ebccc822 ARM: dts: Configure interconnect target module for am437x sgx
This seems to be similar to what we have for am335x. The following can be
tested via sysfs with the to ensure the SGX module gets enabled and disabled
properly:

# echo on > /sys/bus/platform/devices/5600fe00.target-module/power/control
# rwmem 0x5600fe00              # revision register
0x5600fe00 = 0x40000000
# echo auto > /sys/bus/platform/devices/5600fe00.target-module/power/control
# rwmem 0x5000fe00
Bus error

Note that this patch depends on the PRM rstctrl driver that has
been recently posted. If the child device driver(s) need to prevent
rstctrl reset on PM runtime suspend, the drivers need to increase
the usecount for the shared rstctrl reset that can be mapped also
for the child device(s) or accessed via dev->parent.
