regulator: rtq2208: Add fixed LDO VOUT property and check that matches the constraints

Browse Source 
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.
