Convert RTC I2C device creation from devm_i2c_new_dummy_device() to
i2c_new_ancillary_device() to enable the use of a device tree-specified
RTC address instead of a hardcoded value. If the device tree does not
provide an address, use hardcoded values as a fallback.
This addresses an issue with the MAX77663 PMIC, which can have the RTC at
different I2C positions (either 0x48, like the MAX77714, or 0x68, like
the MAX77620). The MAX77620 value is used as the default. The I2C position
of the MAX77663 is factory-set and cannot be detected from the chip
itself.
I have tested this patch on LG Optimus Vu P895 with max77663 PMIC and
non-default RTC position. RTC is registered correctly.

Changes in v4
- adjusted pinconfig node naming
- changed interrupt in the example
- fixed indentation in the example
- corrected pinconfig node name in the example
- commit "dt-bindings: gpio: trivial-gpio: remove max77620 compatible"
squashed with the converting patch for this compatible
Changes in v3
- max77620 files converted to DT schema.
Changes in v2
- dropped patch that changes max77686 and adjusted max77620 where max77663
is described.
