Trivially extend the regulator_register_always_on() helper function to be
even more useful by adding a voltage parameter to it.

Currently regulator_register_fixed() uses a constant name to register a
fixed dummy regulator. This is sufficient in principle, since there is no
reason to register multiple such regulators. The user can simply supply all
consumers in one array and use it to initialise such a regulator. However,
in some cases it can be convenient to register multiple such regulators.
This is also a prerequisite for the upcoming patch, that will add a voltage
parameter to this function. The original function is provided as a wrapper
macro.

When regulator_register_fixed() is being used to register fixed dummy
regulator, the following line will be seen in the boot log. And the
sysfs entry for fixed dummy regulator is not shown.
dummy: Failed to create debugfs directory
The patch renames the fixed dummy supply to "fixed-dummy" to avoid
the name collision with dummy regulator.

Some devices require a regulator to work, but boards may not have
a software controllable regulator for this device. Provide a helper
function to make it simpler for these boards to register a fixed
regulator as a dummy regulator.
