mtd: nand: ecc-mtk: handle ECC clock enable failures

mtk_ecc_get() gets a reference to the ECC platform device, obtains the
provider state and then enables the ECC clock before initializing the
hardware.

The clk_prepare_enable() return value is currently ignored.  If enabling
the clock fails, the code still touches the ECC registers and returns a
live ECC handle to the caller.  The provider device reference acquired
by of_find_device_by_node() is also kept even though the handle setup
failed.

Propagate the clock enable error and drop the provider device reference
on that failure path.
