*
* Modem is initially disabled and does not start automatically.
* Enable power and start modem by "pressing" POWER_ON_OFF input for 1.0s.
* TOBY-L2 series can be switched on in one of the following ways:
* - Rising edge on the VCC pin to a valid voltage for module supply,
* i.e. applying module supply
* - Low level on the PWR_ON pin, which is normally set high by an
* internal pull-up, for a valid time period when the applied VCC
* voltage is within the valid operating range (see section 4.2.8).
* - Low level on the RESET_N pin, which is normally set high by an
* internal pull-up, for a valid time period when the applied VCC
* voltage is within the valid operating range (see section 4.2.9).
*
* PWR_ON low time: 5 ms - Low time to switch-on the module
* RESET_N low time: 18..800 ms - Low time to switch-on the module
* 2.1..15 s - Low time to reset the module
* 16 s - Low time to switch-off the module

* - HUAWEI ME909s Series LTE LGA Module Hardware Guide, Issue 02, Date 2016-02-20

* 4.2.8 PWR_ON pin

*
* Functionality:
* - Leave GSM power enable as is (default at power up = off)
* - Set reset line inactive (note: inverter logic in HW present)
* - Leave button unpressed (note: inverter logic in HW present)
* - Modem shall be enabled by Linux system by enabling GSM power
