ARM: ux500: Elaborate on SDI device node names in Device Tree

In the DB8500 Reference Manual SDI devices are described as being
part of peripheral blocks. This is more in line with how these devices
are actually represented in hardware, so here we detail which
peripheral block each of the SDI devices belong in the node name.
