mtd: rawnand: pl353: fix clk reference leak in pl35x_nfc_setup_interface()

pl35x_nfc_setup_interface() obtains a reference to the SMC "memclk" with
of_clk_get_by_name() and only uses it to read the clock rate. The
reference is never released: the function has many early return paths
and no clk_put() call anywhere, so the clock reference is leaked.

The hook is invoked repeatedly by the NAND core (nand_reset(),
nand_setup_interface() and the NAND_DATA_IFACE_CHECK_ONLY mode probing
loops), so the reference count keeps growing.

Release the clock reference with clk_put() as soon as its rate has been
read.
