24c9cd8f8d mtd: oxnas_nand: Handle clk_prepare_enable/clk_disable_unprepare. 
- clk_prepare_enable() can fail here and we must check its return value.
 - oxnas_nand_probe() can fail here and we must disable clock.

b98e1995e4 mtd: oxnas_nand: Allocating more than necessary in probe() 
We only need to allocate sizeof(struct oxnas_nand_ctrl) which is 192
bytes and not sizeof(struct nand_chip) which is a much larger 3056
bytes.
