Subject: [PATCH v3 1/3] w1: mxc_w1: Adapt the clock name to the new clock framework

With the new i.mx clock framework the mxc_w1 clock is registered as:

clk_register_clkdev(clk[owire_gate], NULL, "mxc_w1.0");

So we do not need to pass "owire" string and can use NULL instead.

While at it, also fix the clock error handling code.
