[PATCH v3 1/3] arm64: dts: qcom: sm8250-xiaomi-elish: Add pm8008 PMIC

[Xin Xu <xxsemail@qq.com>]

Add the pm8008 PMIC node on i2c15 with seven LDOs,
using GPIO84 as interrupt and GPIO76 as reset.

Changes in v3:
  - Split pinctrl into two separate states for interrupt and reset, drop
    input-enable.
  - Reorder bias properties after drive-strength.

Changes in v2:
  - Fix coding style (blank line, interrupts-extended, property order,
    drop output-high)
  - Correct voltage constraints for ldo1 and ldo2
