i2c: viai2c-wmt: Fix clock leak in wmt_i2c_probe()

Browse Source 
In wmt_i2c_probe(), i2c->clk is acquired using of_clk_get(). If any
subsequent operation fails or when the module is unloaded, the clock
reference count is never decremented via clk_put(), leading to a
resource leak.

Switch to devm_clk_get() so that the clock is automatically managed
and released.
