Add the reset-gpio toggling in the pm8008_probe() to bring
pm8008 chip out of reset instead of doing it in DT node using
"output-high" property.

Changes in V13:
- None.
Changes in V12:
- Move reset_gpio acquiring above probe_irq_peripherals in pm8008_probe.
Changes in V11:
- Use local variable for reset_gpios as it is not used outside of probe.
- Use GPIOD_OUT_LOW flag to initialize the gpio and remove below line
as it is not required "gpiod_set_value(chip->reset_gpio, 1);".
