On some boards, the TPS2388x's reset line (active low) is pulled low to
keep the chip in reset until the SoC pulls the device out of reset.
This series updates the device-tree binding for the tps23881 and then
adds support for the reset gpio handling in the tps23881 driver.

v1 -> v2:
  - Changed the reset pulse duration to be between 5us and 10us, per the
    TPS23880 datasheet
  - Changed the delay after reset to be 50ms instead of 1-10ms in order
    to meet the minimum recommended time before SRAM programming.

v1: https://lore.kernel.org/netdev/20240819190151.93253-1-kyle.swenson@est.tech/
