mtd: nand: orion: fix clk handling
commit 675b11d94ce9baa5eb365a51b35d2793f77c8ab8 upstream.
The clk handling in orion_nand.c had two problems:
- In the probe function, clk_put() was called for an enabled clock,
which violates the API (see documentation for clk_put() in
include/linux/clk.h)
- In the error path of the probe function, clk_put() could be called
twice for the same clock.
In order to clean this up, use the managed function devm_clk_get() and
store the pointer to the clk in the driver data.
