[EricR Lai (Code Review)]

Hello Patrick Georgi, Martin Roth, Marco Chen,

I'd like you to reexamine a change. Please visit

......................................................................

mb/google/octopus/variants/fleex: support LTE power sequence

GPIOs related to power sequence are
  GPIO_67  - EN_PP3300
  GPIO_117 - FULL_CARD_POWER_ON_OFF
  GPIO_161 - PLT_RST_LTE_L
1. Power on: GPIO_67 -> 0ms -> GPIO_117 -> 30ms -> GPIO_161
2. Power off: GPIO_161 -> 30ms -> GPIO_117 -> 100ms -> GPIO_67
3. Power reset:
  - keep GPIO_67 and GPIO_117 high and
  - pull down GPIO_161 for 30ms then release it.

BUG=b:168075958
BRANCH=octopus
TEST=build image and verify on the DUT with LTE DB.
