This patch adds DT support for parsing regulators constraints for parent(mfd)
node and moves some common intialising code out of loop while registering.

Implementing set_ramp_rate() and using standard constraints for getting
ramp_delay and ramp_disable, instead of getting it as s2mps11 specific data
through platform data, makes driver more compliant with framework and reduces
the complexity for adding DT support.

Currently driver uses local struct s2mps11_info to store ramp rate for bucks
whic its getting through platform data, so instead of using regulator
constraints it should use s2mps11_info to calculate ramp delay.

This patch makes driver to use uV/us as units of ramp_delay. It makes driver
in compliance with regulator framework and make ramp rate precise.
This patch also sets default ramp rate in regulator descriptor which can be
used in case if case ramp rate is not set in regulator constraints.

All the drivers that need delay for the regulator voltage output voltage to
stabilize after being enabled or after being set to a new value has been
converted to implement enable_time and set_voltage_time_sel callbacks.
Then regulator core will take care of the necessary delay.
This patch removes the unneeded include of linux/delay.h in regulator drivers.

Currently s2mps11->iodev, s2mps11->dev and config.dev point to NULL.
This patch fixes the settings for config.dev.
Current code does not need the *dev and *iodev of struct s2mps11_info,
so remove them.
