The SGX IP is valid and usable on AM438x devices, enable this
here.

Didn't see the parent node didn't make upstream this cycle, ignore for
now, sorry for the noise.

This still produces:

arch/arm/boot/dts/am43x-epos-evm.dts:796.1-5 Label or
path sgx not found

The parent node for the interconnect target module can be added
the same ways as done in "ARM: dts: Add nodes for missing omap4
interconnect target modules". But the child sgx device binding
still needs to be documented before we can add those.

Tony
