soc: qcom: smd-rpm: Move icc_smd_rpm registration to clk-smd-rpm

icc_smd_rpm will do bus clock votes itself rather than taking the
unnecessary detour through the clock subsystem. However, it can only
do that after the clocks have been handed off and scaling has been
enabled in the RPM in clk-smd-rpm.

Move the icc_smd_rpm registration from smd-rpm.c to clk-smd-rpm.c
to avoid any possible races. icc_smd_rpm gets the driver data from
the smd-rpm device, so still register the platform device on the
smd-rpm parent device.
