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.

This patch implements set_suspend_disable callback for BUCKs which
support only switch ON/OFF modes during system suspend state, and
set_suspend_mode callbacks for LDOs which also suport Low power mode and
switch ON/OFF modes.Signed-off-by: Yadwinder Singh Brar

This patch converts the driver to use regulator_set_voltage_time_sel() as
.set_voltage_time_sel() callback. It also sets ramp_delay as 100000 uV/us for
LDOs & normal BUCKs and 27500 uV/us(default/reset value) for BUCKs[2/3/4] in
regulator_desc[].Signed-off-by: Yadwinder Singh Brar

rdev->desc->uV_step * abs(new_selector - old_selector) returns uV.
The unit of ramp_rate is mV/us.
Thus 1000 should be multiplied.Signed-off-by: Axel Lin

Both max77686_ops and max77686_buck_dvs_ops use simple linear voltage maps.
