The min_uV and max_uV are not really used in the code and misleading because
the min_uV and max_uV settings does not match the value in the voltage table.
For example, we have
static const unsigned int ldo_vaux3_voltages[] = {
1200000,
1500000,
1800000,
2100000,
2500000,
2750000,
2790000,
2910000,
};
With below min_uV/max_uV settings for AB8500_LDO_AUX3.
.min_uV = 1100000,
.max_uV = 3300000,
The min_uV/max_uV for AB8500_LDO_AUX3 seems copy-paste from AB8500_LDO_AUX2
and is wrong.

Also removes set_voltage_time_sel callback from ab8500_regulator_fixed_ops
because the voltage won't change. ( And ab8500_regulator_fixed_ops does not
implement get_voltage_sel so set_voltage_time_sel won't be called )

The 'name' field in 'struct of_regulator_match' expects to match with
its corresponding regulator device node in the Device Tree. This patch
renames each of the regulators in the ab8500 regulator driver so this
is true.

Here we setup the ab8500 regulator driver for DT. We first do
this in the normal way, by providing a match structure during
initialisation, but then we provide information so that
whilst probing we can use existing data structures to do DT
look-ups.

ab8500's probe() function is becoming quite large, so in the lead
up to Device Tree enablement which will fork the thread of execution
this patch splits it into 3 main areas; basic error checking will
remain in probe(), but regulator register initialisation and regulator
registration have been moved to their own functions which will
be called in sequence by probe() and the DT equivalent.

Rather than adding new arguments to regulator_register() every time we
want to add a new bit of dynamic information at runtime change the function
to take these via a struct. By doing this we avoid needing to do further
changes like the recent addition of device tree support which required each
regulator driver to be updated to take an additional parameter.
The regulator_desc which should (mostly) be static data is still passed
separately as most drivers are able to configure this statically at build
time.

With device tree support for regulators, its needed that the
regulator_dev->dev device has the right of_node attached.
To be able to do this add an additional parameter to the
regulator_register() api, wherein the dt-adapted driver can
then pass this additional info onto the regulator core.

The define for number of regulators is moved from ab8500-core to
ab8500-regulator so that the regulator driver can be updated
independently of ab8500-core. This also changes the platform
configuration structure of ab8500-core so that it contains a
pointer to the regulator_init_data array plus number of
regulators instead of an fixed size array of pointers to
regulator_init_data.

Change the interface used by set_voltage() to report the selected value
to the regulator core in terms of a selector used by list_voltage().
This allows the regulator core to know the voltage that was chosen
without having to do an explict get_voltage(), which would be much more
expensive as it will generally access hardware.
