Re: [PATCH 4/4] clk: qcom: rpm: drop the platform from clock definitions

A single clock definition can be used on different platforms. Thus the
platform part of the clock name is not correct (and can be misleading).

Remove the platform-specific part of the defined clock.

Again, I like what you're trying to do but I'll wait until you've
had a chance to try to address my comments on patch 3 to comment
further.
