ufs: Disable UTP command timeout in slow mode
When the UFS controller is operating in slow (PWM) mode,
the driver is disabled the timeout for UTP send commands.
In high-speed mode, the timeout remains enabled to
detect stalled or failed transfers. This change ensures reliable
operation in slow mode, where command completion may take longer
and timeouts are not required.
