regulator: mp886x: Convert to use regulator_set_ramp_delay_regmap
Use regulator_set_ramp_delay_regmap instead of open-coded.

regulator: mp886x: use "mps,switch-frequency-hz"
As Rob suggested, use the "mps,switch-frequency-hz" instead of the
"mps,switch-frequency" for switch frequency. Fortunately, the switch
frequency support isn't released, so we can modify it now without
any concern.

regulator: mp886x: implement set_ramp_delay
Implement the .set_ramp_delay for MP8867 and MP8869. MP8867 and MP8869
could share the implementation, the only difference is the slew_rates
array.

regulator: mp886x: use .probe_new
Use the new .probe_new for mp886x. It does not use the const
struct i2c_device_id * argument, so convert it to utilise the
simplified i2c driver registration.

regulator: mp886x: add MP8867 support
MP8867 is an I2C-controlled adjustable voltage regulator made by
Monolithic Power Systems. The difference between MP8867 and MP8869
are:
1.If V_BOOT, the vref of MP8869 is fixed at 600mv while vref of
MP8867 is determined by the I2C control.
2.For MP8867, when setting voltage, if the step is within 5, we
need to manually set the GO BIT to 0.

regulator: add support for MP8869 regulator
The MP8869 from Monolithic Power Systems is a single output DC/DC
converter. The voltage can be controlled via I2C.
