[PATCH v7 0/3] Add support for Richtek RT9455 battery charger

[Anda-Maria Nicolae <anda-maria.nicolae@intel.com>]

The next 3 patches do the following:
- first patch adds Richtek Technology Corporation in the vendor-prefixes list
- second patch adds device tree binding example for Richtek RT9455 battery charger
- third patch adds the driver for Richtek RT9455 battery charger

The reason why v6 did not contain any modification except for patch splitting, is that
I did not scroll down the e-mail and I thought the patch splitting was the only modification
I need to do. My bad.

Updates from v6:
- added interrupt-parent and interrupts as required properties in DT file rt9455_charger.txt.
- removed interrupt-gpio and reset-gpio from DT file rt9455_charger.txt.
- used IRQ_TYPE_LEVEL_LOW (for this charger, it works the same with IRQ_TYPE_EDGE_RISING and
  with IRQ_TYPE_LEVEL_LOW, but I prefer IRQ_TYPE_LEVEL_LOW) in interrupt specification, 
  in DT file rt9455_charger.txt.
- removed gpiod_irq and gpio_irq from rt9455_info structure.
- set boost voltage value without previously reading the existing value in the register.
- set voreg value without previously reading the existing value in the register.
- removed rt9455_setup_irq function. client->irq is set even without calling of_irq_get().
- used devm_power_supply_register() and removed power_supply_unregister() from rt9455_remove().
