mb/google/octopus/variants/bobba: support LTE power sequence
GPIOs related to power sequnce 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:144327240
BRANCH=octopus
TEST=build image and verify on the DUT with LTE DB.
