escc.c: add empty ranges property to escc and escc-legacy nodesofficial
This fixes an intermittent panic in the AppleSCCSerial module for MacOS
10.2 and the g3beige machine during initialisation as the module tries to
write to the on-chip registers at 0x130XX rather than calculating the
correct address derived from the parent PCI node.
As described in the IEEE-1275 specification: if a "ranges" property exists but
has a zero-length property value, the child address space is identical to the
parent address space.
