mb/google/octopus/variants/dood: support LTE module
related LTE GPIOs: 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.
