can: at91_can: add missing prepare and unprepare of the clock
commit e77980e50bc2850599d4d9c0192b67a9ffd6daac upstream.
In order to make the driver work with the common clock framework, this patch
converts the clk_enable()/clk_disable() to
clk_prepare_enable()/clk_disable_unprepare(). While there, add the missing
error handling.
