sconfig: Apply 'hidden' state from override tree
In order to allow override trees to hide/unhide a device copy the hidden state to the base device. This allows a sequence of states like:
chipset.cb: mark device 'off' by default devicetree.cb: mark device 'hidden' (to skip resource allocation) overridetree.cb: mark device 'on' for device present on a variant
BUG=b:159143739 BRANCH=volteer TEST=build volteer variants with TCSS RP0 either hidden or on and check the resulting static.c to see if the hidden bit is set appropriately.
