Allow a user to write pwm oneshot_count value. If oneshot_count == 0,
the pwm works in continuous mode. If 0 < oneshot_count < 256, the
pwm works in oneshot mode.

The oneshot_count value should be less than PWM_ONESHOT_COUNT_MAX.
If oneshot_count == 0, this pwm channel works in continuous mode.

Most SOCS have only 8 or 6 channels, but have more than 16
peripherals. If those peripherals work together, some
fails to request dma channel, because there are no enough
channels. And maybe it's unnecessary to use dma for uart
tx. It is necessary for uart rx when hardware auto flow
control is not used.
&uart0 {
dma-names = "!tx", "rx"; // disable uart tx with dma
status = "okay";
};

To avoid "too much work for irq" issue, cherry pick the patch.
It reads the RBR to clear the time out interrupt, but sometime the
rx fifo may be not empty while cpu reads the RBR. Which would cause
the data lost.

By the way, current patch can't get rid of the risk entirely, so I
try a lot to solve it. Unfortunately, I only got the phenomenon that
lower pclk can reduce the probability. And I check the dw data sheet,
it has pclk and sclk, so there is synchronization problem. But it
only requires (slck < 4*pclk).

The clk_get_rate function is used in pwm_apply and pwm_config.
And it is not allowed in interrupt calls due to a mutex.
So move it into pwm_probe function.

If some PWM enable_conf was configured with different values at
uboot/loader, the enable_conf should be cleaned firstly and
configured them at kernel. It is better to use the same parameters
on both sides to ensure excessive smoothing.
