Add driver for TI BQ25630 charger

This patch series contains a fully working driver for the basic functionality for the new TI BQ25630 charger (see datasheet [1]). The other "advanced" functionalities such as USB OTG, BATFET control and liquid detection, will be handled in separate patches (after necessary framework changes) according to the design discussions in the first RFC version.

Changes in v3:

[power]
* Sort variable declarations in reverse x-mas tree order in read/write property functions.

[dt-bindings]
* Drop description for property reg.
* Remove | in description for property interrupts.
* Remove monitored-battery from properties.
* Use unevaluatedProperties: false instead of additionalProperties: false.

Changes in v2:

[power]
* Fix return value check for data->regmap16be initialization in probe (check was wrongly for data->regmap16le).
* Remove TODO-comment about BATFET sysfs ABI (we will add a new sysfs ABI entry in the framework for this).
* Check registers BQ25630_REG_CHARGER_STATUS_X as well in IRQ handler. Because there might be changes that is not necessarily *only* triggered from hardware faults. For example, manually enabling/disabling with echo 0 > /online.

[dt-bindings]
* Rename file with ti, prefix.
* Remove battery-node in example.
