video: fbdev: pxa168fb: Use devm_clk_get
This patch introduces the use of managed resource function devm_clk_get instead of clk_get and removes corresponding calls to clk_put in the probe and remove functions. To be compatible with the change various gotos are replaced with direct returns, and unneeded label failed_put_clk is dropped.
