ARM: dts: qcom: apq8064: Drop redundant /smd node

The "smd-edge"s for remote processors are typically specified below the
remoteproc nodes. For some reason apq8064 also has them all listed in a
top-level /smd node, disabled by default. None of the boards enable them.

Right now apq8064 only has support for WCNSS/riva, but there the
smd-edge is already defined with the same interrupt etc below the
riva-pil node.

Drop these redundant definitions since the /smd top-level node is now
deprecated.
