 regulator: twl: voltage lists for vdd1/2 on twl4030 
_opp_supported_by_regulators() wrongly ignored errors from
regulator_is_supported_voltage(), so it considered errors as
success. Since
commit 4982094451 ("regulator: core: simplify return value on suported_voltage")
regulator_is_supported_voltage() returns a real boolean, so
errors make _opp_supported_by_regulators() return false.

That reveals a problem with the declaration of the VDD1/2
regulators on twl4030.
The VDD1/VDD2 regulators on twl4030 are neither defined with
voltage lists nor with the continuous flag set, so
regulator_is_supported_voltage() returns false and an error
before above mentioned commit (which was considered success)
The result is that after the above mentioned commit cpufreq
does not work properly e.g. dm3730.

[    2.490997] core: _opp_supported_by_regulators: OPP minuV: 1012500 maxuV: 1012500, not supported by regulator
[    2.501617] cpu cpu0: _opp_add: OPP not supported by regulators (300000000)
[    2.509246] core: _opp_supported_by_regulators: OPP minuV: 1200000 maxuV: 1200000, not supported by regulator

[    2.537750] cpu cpu0: _opp_add: OPP not supported by regulators (800000000)

The patch fixes declaration of VDD1/2 regulators by
adding proper voltage lists.

Linux kernel
============

There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.

In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``.  The formatted documentation can also be read online at:

    https://www.kernel.org/doc/html/latest/

There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.

Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
