The regulator_desc never need to be modified, so define them as const as a
hint to the compiler that they can go into .rodata.

The regulator_desc arrays in this driver are indexed by RN5T618_*
constants and some elements can be missing. This causes probe failures
on older models:
rn5t618-regulator rn5t618-regulator: failed to register (null) regulator
rn5t618-regulator: probe of rn5t618-regulator failed with error -22
Fix this by making the arrays flat. This also saves a little memory
because the regulator_desc arrays become smaller.

Extend the driver to support Ricoh RC5T619.
Support the additional regulators and slightly different voltage ranges.

Declare regulator_ops structure as const as it is only stored in the ops
field of a regulator_desc structure. This field is of type const, so
regulator_ops structures having this property can be made const too.

Use the simplified DT parsing method to remove some duplicated
code.
Since this is a MFD subdevice and its device object doesn't have an
associated DT node, the configuration instance used to register the
regulators has been changed to point to the parent device.
