clk: qcom: drop the SC7180 Modem subsystem clock driver

This driver has never been used in the DT files merged to the kernel.
According to Sibi, it only worked on the pre-production devices. For the
production devices this functionality has been moved to the firmware.

Drop the driver to remove possible confusion.
