constraints
A fixed LDO VOUT property has been added to specify the fixed_uV of the regulator_desc.
Additionally, a check has been included in this version
to ensure that the fixed_uV matches the constraints.

In this patch, LDO's adjustable and fixed Vout settings are compatible.
The LDO Vout ability depends on "richtek,fixed-microvolt".
If adjustable, the Vout can be set to either 1800mV or 3300mV.

devm_of_regulator_put_matches is called
In this patch, a software bug has been fixed.
rtq2208_ldo_match is no longer a local variable.
It prevents invalid memory access when devm_of_regulator_put_matches
is called.

Pull regulator updates from Mark Brown:
"There's one API update here, a new API factoring out a common pattern
for reference voltage supplies. These are supplies used as a reference
by analogue circuits where the consumer requests and enables the
supply, reads the voltage to calibrate the user and then never touches
it again. This is factored out into a single operation which just
returns the voltage and uses devm_ to manage the request and enable
portion.
Otherwise this has been a very quiet release, we've got some new
device support, some small fixes, housekeeping and cleanup work but
nothing substantial.
There's also some non-regulator changes in here, a number of users for
the new reference voltage API were merged along with it and some MFD
changes were pulled in as dependencies for new driver work.
Highlights:
- Add a new API for single operation handling of reference voltages
- Support for Allwinner AXP717 and D1, and NXP PCA9561A"

The LDO's Vout is adjustable if the hardware setting allows it,
and it can be set either 1800mv or 3300mv.
Additionally, the discharge register has been moved to another position.

The maximum ramp up and down range of BUCK are shorten
from 64mVstep/us to 16mVstep/us.
Therefore, the RTQ2208_RAMP_VALUE_MAX_uV is modified
to 16000uV in this version.

struct i2c_driver::probe_new is about to go away. Switch the driver to
use the probe callback with the same prototype.
