pinctrl: stm32: Fix the unit of the hwspinlock timeout
HWSPNLCK_TIMEOUT is passed to hwspin_lock_timeout_in_atomic(), whose
timeout argument is in milliseconds, not microseconds:
atomic_delay += HWSPINLOCK_RETRY_DELAY_US;
if (atomic_delay > to * 1000)
return -ETIMEDOUT;
The hwspinlock core documents this explicitly:
If the mode is HWLOCK_IN_ATOMIC (called from an atomic context) the
timeout is handled with busy-waiting delays, hence shall not exceed
few msecs.
Fixes: 290a9f937e5a ("pinctrl: stm32: use the hwspin_lock_timeout_in_atomic() API")
