syscon.yaml uses select if compatible contains "syscon", so use select
here too ??

When there are no other combinations then with syscon and simple-mfd
then there's no need for "oneOf", but a look in the build log shows
there are 2 (3) exceptions:

#cat build-dtbs-1471909.log | grep short
rv1108-elgin-r1.dt.yaml: syscon@202a0000: compatible:
['rockchip,rv1108-usbgrf', 'syscon'] is too short
rk3288-evb-act8846.dt.yaml: syscon@ff740000: compatible:
['rockchip,rk3288-sgrf', 'syscon'] is too short

rockchip,rv1108-pmugrf was never added to a document.

		reg = <0x20060000 0x1000>;
