ARM: dts: qcom: Add support for a 'socketed CDP' platform subtype (0x1)

Socketed CDPs (CDPs where the SoC is in a socket rather than
soldered-down) are being assigned a separate platform subtype to
allow software to restrict DDR frequencies to ranges which work
reliably with the sockets. These restrictions are taken care of
RPM software and needs not affect Linux behavior, so simply have
socketed CDPs share device trees with soldered CDPs.
