The TPS65218 chip is a power management IC for Portable Navigation Systems
and Tablet Computing devices. It contains the following components:

 - Regulators.
 - Over Temperature warning and Shut down.

This patch adds support for tps65218 mfd device. At this time only
the regulator functionality is made available.

This changes the following mechanisms in the TC3589x device tree
probing path:

- Use the .of_match_table in struct device_driver to match the
  device in the device tree.
- Add matches for the proper compatible strings "toshiba,..."
  and all sub-variants, just as is done for the .id matches.
- Move over all the allocation of platform data etc to the
  tc3589x_of_probe() function and follow the pattern of passing
  a platform data pointer back, or an error pointer on error,
  as found in the STMPE driver.
- Match the new (proper) compatible strings for the GPIO and
  keypad MFD cells.
- Use of_device_is_compatible() rather than just !strcmp()
  to discover which cells to instantiate.

It is currently not possible to select the SA1100 or Vexpress
drivers in the MFD subsystem, because the menu for the entire
subsystem ends before these options are presented.

Move the main menu closing and the endif for HAS_IOMEM to the
end of the file so these are selectable again.

During probe the sec-core driver allocates dummy I2C device for RTC with
i2c_new_dummy() but return value is not checked. In case of error
(i2c_new_device(): memory allocation failure or I2C address cannot be
used) this function returns NULL which is later used by
devm_regmap_init_i2c() or i2c_unregister_device().

If i2c_new_dummy() fails for RTC device, fail also the probe for main
MFD driver.
