H. Nikolaus Schaller April 24, 2020, 8:34 p.m. UTC 
Add SGX GPU node with interrupt. Tested on PandaBoard ES.

Since omap4420/30/60 and omap4470 come with different SGX variants
we need to introduce a new omap4470.dtsi. If an omap4470 board
does not want to use SGX it is no problem to still include
omap4460.dtsi.
