<div class='commit-subject'>regulator: pwm: Add support to have multiple instance of pwm regulator</div><div class='commit-msg'>Some of platforms like Nvidia's Tegra210 Jetson-TX1 platform has
multiple PMW based regulators. Add support to have multiple instances
of the driver by not changing any global data of pwm regulator and
if required, making instance specific copy and then making changes.
