This patch modifies the platform data of max8998 to use arrays for
specifying predefined voltages of buck1 and buck2 instead of separate
field for each voltage.

This allows to simplify the code a bit and will help in adding support
for Device Tree, which will be introduced in further patch.

This patch adds irq domain support for max8998 interrupts.

To keep both non-DT and DT worlds happy, simple domain is used, which is
linear when no explicit IRQ base is specified and legacy, with static
mapping, otherwise.

The Patch adds TPS659038 PMIC support in the palmas mfd driver.
The TPS659038 has almost the same registers as of the earlier
supported variants of PALMAS family such as the TWL6035.

The critical differences between TPS659038 and TWL6035 being:

1) TPS659038 has nothing related to battery charging and back up battery stuff.
2) TPS659038 does not have does not have SMPS10(Boost) step up convertor.
3) TPS659038 does not have Battery detection and anything related to battery.
4) SD card detection, Battery presence detection, Vibrator, USB OTG are missing
   when compared to TWL6035.

The TWL6025 was never released beyond sample form and was replaced by
the PhoenixLite range of chips - TWL6032. Change the references to
reference the TWL6032 class and name the registers to twl6032 in line with
an actual released chip name to avoid confusion.

Currently there are no users of TWL6025 in the code.

The driver can be used on either arm or arm64 platforms, but
the latter doesn't have any platform-specific configuration
options, so it must be possible to manually enable the driver.

As the gpiolib is optional for arm64 arch, the gpio/led code
must be compiled conditionally.

Use devm_ioremap_resource and devm_kzalloc to simplify error
paths and reduce lines of code. Also use dev_err() to keep
consistency and drop the .remove function because the devm
functions take care of what it's doing besides the now obsolete
platform_set_drvdata() which we can just drop. Finally, use
module_platform_driver() to save some more lines.

The genirq IRQ wake method will default to failure if the irq_chip
does not provide a set_wake method.  However, for TWL4030 sub-chip
IRQs, we want the wake enable to succeed even though we don't provide
a set_wake method.  This allows sub-chip IRQs to still be flagged as
wakeup capable, and allow them to wakeup from suspend (or abort
suspend if they fire during suspend.)

To fix, use the IRQCHIP_SKIP_SET_WAKE flag in the irq_chip.

A complete refurbished series inclunding:
- DT support for the MFD, TSC and ADC driver & platform device support,
  which has no users, has been killed.
- iio_map from last series is gone and replaced by proper nodes in the
  device tree.
- suspend fixes which means correct data structs are taken and no
  interrupt storm
- fifo split which should problem with TSC & ADC beeing used at the same
  time
- The ADC channels are now checked before blindly applied. That means the
  touch part reads X, Y and Z coordinates and does not mix them up. Same
  goes for the IIO ADC driver.
- The IIO ADC driver now creates files named in_voltageX_raw where X
  represents the ADC line instead of a number starting at 0. A read from
  this file can return -EBUSY in case touch is busy and the ADC didn't
  collect a value.
