staging: media: omap1: Replace clk_get with devm_clk_get

devm_clk_get allocated resources get released when a driver detaches.
Replace clk_get with devm_clk_get and remove corresponding data
releasing function clk_put from probe and remove functions of a
platform device. Also remove an unnecessary label.

This change was made with the help of the following Coccinelle
semantic patch:
@platform@
identifier p, probefn, removefn;
@@
struct platform_driver p = {
  .probe = probefn,
  .remove = removefn,
};

@prb@
identifier platform.probefn, pdev;
expression e;
@@
probefn(struct platform_device *pdev, ...) {
  ...
  e =
- clk_get
+ devm_clk_get
  (...);
   ...
?- clk_put(...);
  ...
}
@remove depends on prb@
identifier platform.removefn;
@@
removefn(...) {
...
?- clk_put(...);
...
}
