cheza: Add SDM845 power sequence for rev-0 board

This is the power sequence for rev-0 board. Confirmed the behavior of
reprogramming the PMIC registers to enable the instant reset and
shutdown.

BRANCH=none
BUG=b:74395451
TEST=make buildall -j
TEST=Tried the following cases:
* Cold reset:
  $ dut-control cold_reset:on sleep:0.2 cold_reset:off
  Result: G3 -> S0
* Long power press to shutdown:
  $ dut-control pwr_button:press sleep:8.2 pwr_button:release
  Result: S0 -> S5 -> G3
* Long power press to power-on but then shutdown:
  $ dut-control pwr_button:press sleep:8.2 pwr_button:release
  Result: G3 -> S0 -> S5 -> G3
* Short power press to power-on:
  $ dut-control pwr_button:press sleep:0.2 pwr_button:release
  Result: G3 -> S0
* Console command: apreset
  Result: S0 -> S5 -> S0
* Console command: power off
  Result: S0 -> S5 -> G3
* Console command: power on
  Result: G3 -> S0
* Console command: apshutdown
  Result: S0 -> S5 -> G3
* Lid open to power-on:
  $ dut-control lid_open:no sleep:0.2 lid_open:yes
  Result: G3 -> S0
