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.

For now, the call to twl4030-power is hard-wired inside twl-core.

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.
