[PATCH v2] clk: mvebu: armada-37xx-tbg: Switch to clk_get and balance it in probe

[Gregory CLEMENT]

The parent clock is get only to have its name, and then the clock is no
more used, so we can safely free it using clk_put. Furthermore as between
the successful devm_clk_get() and the devm_clk_put() call we don't exit
the probe function in error so I can use non managed version of clk_get()
and clk_put().

Changelog:
v1 -> v2

 - Use the non managed version of clk_get() and clk_put() (suggested
   by Stephen Boyd)
 - Modify the title and the commit log to reflect this change
