ASoC: convert from clk round_rate() to

Merge series from Brian Masney <bmasney@redhat.com>:

The round_rate() clk ops is deprecated in the clk framework in favor
of the determine_rate() clk ops, so let's go ahead and convert the
drivers in the rtc subsystem using the Coccinelle semantic patch
posted below. I did a few minor cosmetic cleanups of the code in a
few cases.

Coccinelle semantic patch:

    virtual patch

    // Look up the current name of the round_rate function

    identifier round_rate_name =~ ".*_round_rate";

Note that I used coccinelle 1.2 instead of 1.3 since the newer version
adds unnecessary braces as described in this post.
