Do we even want to add SGX to the .dts? We don't have proper drivers for
SGX. If we ever do, who knows what kind of DT data they need. I know the
DT data for SGX in TI's kernel tree has changed at least once.

I don't think reg or interrupts will be removed, so the properties
added by Tony look pretty safe?. I guess if we ever have a driver

Oh, and one more thing about the regs. I believe SGX consists of
multiple register blocks. But as it's not documented in any public docs,
there's just that single block in the DT data. I'm not sure if single
block or multiple blocks would be the right approach, but then, I guess
we can always live with just a single block and if needed split the
blocks inside the driver.

OK, those register blocks can easily be child nodes of the module
if needed. This is for the parent interconnect target module
revc/sysc/syss registers that we already have mapped in legacy
platform data for the interconnect code.

Tony
