Subject: [PATCH v3 0/6] Fix rtq2208 BUCK ramp_delay and LDO dvs setting

Hi,

This series patches is for hardware modification of RTQ2208.
ramp_delay range of BUCK is changed.
The maximum ramp up and down range of BUCK are shorten
 from 64mVstep/us to 16mVstep/us.
The LDO's Vout is adjustable if the hardware setting allow it,
and it can be set either 1800mv or 3300mv.
Additionally, the discharge register has been moved to another position.
In this version, a software bug has been fixed.
rtq2208_ldo_match is no longer a local variable.

Thanks,
Alina yu

Change in v3:
- In Patch 1/2:
	- As discussing in v2 series, 
	  add 'richtek,fixed-microvolt' property to specify the fixed voltage
- In Patch 2/2:
	- Move Fixes to the start of the series
	- Seperate LDO vsel and discharge change to seperate patches
	- Add "richtek,fixed-microvolt" to specify LDO fixed voltage
	- Check specified desc->fixed_uV matches with constraints->min_uV and constraints->max_uV
