Some PWM regulator has the exponential transition in voltage change as
opposite to fixed slew-rate linear transition on other regulators.
For such PWM regulators, add the property for providing the delay
from DT node.
Add DT binding details of the new property
"pwm-regulator-voltage-ramp-time-us" added for providing voltage
transition delay.

This patch is continuation of discussion on patch
regulator: pwm: Fix regulator ramp delay for continuous mode
https://patchwork.kernel.org/patch/9216857/
where is it discussed to have separate property for PWM which has
exponential voltage transition.

This is a really long name. Drop the 'pwm-regulator-' part as it is
redundant. The fact that it is PWM reg specific is captured as it is
documented that way.
We already have the regulator-ramp-delay from the regulator core.
Just wanted to make this (pwm-regulator-voltage-ramp-time-us) for pwm
specific.
Can we have "pwm-regulator-ramp-delay" or "pwm-regulator-settling-time-us"?
