The TPS6598x PD controller provides an active-high hardware reset input
that reinitializes all device settings. If it is not grounded by
design, the driver must be able to de-assert it in order to initialize
the device.
This series adds and documents the reset signal management. It also
includes the basic reset management for initialization and
suspend/resume control.

Changes in v2:
- core.c: minor coding style correction ({} in 'else' after 'if {}')
- ti,tps6598x.yaml: reference to the device instead of the driver in
the commit message.
- Link to v1: https://lore.kernel.org/r/20230912-topic-tps6598x_reset-v1-0-78dc0bf61790@wolfvision.net

If it is not grounded by design, the driver must be able to de-assert it in order to initialize the device. The PD controller is not ready for registration right after the reset de-assertion and a delay must be introduced in that case. According to TI, the delay can reach up to 1000 ms [1], which is in line with the experimental results obtained with a TPS65987D. Add a GPIO descriptor for the reset signal and basic reset management for initialization and suspend/resume.
