clk: imx: pll14xx: fix clk_pll14xx_wait_lock

Browse source 
commit c3a5fd15ed0c1494435e4e35fbee734ae46b5073 upstream.

The usage of readl_poll_timeout is wrong, the 3rd parameter(cond)
should be "val & LOCK_STATUS" not "val & LOCK_TIMEOUT_US",
It is not check whether the pll locked, LOCK_STATUS reflects the mask,
not LOCK_TIMEOUT_US.
