Another group of drivers that are taking advantage of the implicit
presence of module.h -- and will break when we pull the carpet out
from under them during a cleanup. Fix 'em now.

Now that we have a shared API between the DB8500 and DB5500
PRCMU's, switch to using this neutral API instead. We delete the
parts of db8500-prcmu.h that is now PRCMU-neutral, and calls will
be diverted to respective driver. Common registers are in
dbx500-prcmu-regs.h and common accessors and defines in
<linux/mfd/dbx500-prcmu.h> This way we get a a lot more
abstraction and code reuse.

In the case where _regulator_enable returns an error it was not checked
if a supplying regulator exists before trying to disable it, leading
to a null pointer-dereference if no supplying regulator existed.

This patch adds support for regulators that can be controlled via gpios.
Examples for such regulators are the TI-tps65024x voltage regulators
with 4 fixed and 1 runtime-switchable voltage regulators
or the TI-bq240XX charger regulators.
The number of controlling gpios is not limited, the mapping between
voltage/current and target gpio state is done via the states map
and the driver can be used for either voltage or current regulators.
A mapping for a regulator with two GPIOs could look like:
gpios = {
{ .gpio = GPIO1, .flags = GPIOF_OUT_INIT_HIGH, .label = "gpio name 1" },
{ .gpio = GPIO2, .flags = GPIOF_OUT_INIT_LOW, .label = "gpio name 2" },
}
The flags element of the gpios array determines the initial state of
the gpio, set during probe. The initial state of the regulator is also
calculated from these values
states = {
{ .value = volt_or_cur1, .gpios = (0 << 1) | (0 << 0) },
{ .value = volt_or_cur2, .gpios = (0 << 1) | (1 << 0) },
{ .value = volt_or_cur3, .gpios = (1 << 1) | (0 << 0) },
{ .value = volt_or_cur4, .gpios = (1 << 1) | (1 << 0) },
}
The target-state for the n-th gpio is determined by the n-th bit
in the bitfield of the target-value.

There are two sets of defines for the REG_CTRL2 bitfields and one
of them has TPS65023_REG_CTRL2_DCDC1 defined incorrectly. Remove
the duplicates and leave the correct one for TPS65023_REG_CTRL2_DCDC1.
This fixes the following sparse warnings:
drivers/regulator/tps65023-regulator.c:77:9: warning: preprocessor token TPS65023_REG_CTRL2_DCDC1 redefined
drivers/regulator/tps65023-regulator.c:70:9: this was the original definition

schedule_delayed_work() returns a bool indicating if the work was already
queued when it succeeds so we need to squash a true down to zero.

It is a reasonably common pattern for hardware to require some delay after
being quiesced before the disable has finalised, especially in mixed signal
devices. For example, an active discharge may be required to ensure that
the circuit starts up again in a known state. Avoid having to implement
such delays in the regulator API by providing regulator_deferred_disable()
which will do a regulator_disable() a specified number of milliseconds
after it is called.
Due to the reference counting done on regulators a deferred disable can
be cancelled by doing another regulator_enable().

TPS65023 is using VDCDC1 as core regulator and TPS65021 is using VDCDC3.
Core-regulator and voltage-tables may differ between
different regulators. These two is now passed as driver data.
