ARM: mvebu: mvebu-soc-id: add missing clk_put() call

The mvebu-soc-id code in mach-mvebu/ needs to enable a clock to read
the SoC device ID and revision number. To do so, it does a clk_get(),
then a clk_prepare_enable(), reads the value, and disables the clock
with clk_disable_unprepare(). However, it forgets to clk_put() the
clock. This commit fixes this issue.
