mb/google/dedede/var/boten: Add LTE power on/off sequence
LTE module used in boten has a specific power on/off sequence.
GPIOs related to power sequnce are:
* GPP_A10 - LTE_PWR_OFF_R_ODL
* GPP_H17 - LTE_RESET_R_ODL
1. Power on: GPP_A10 -> 20ms -> GPP_H17
2. Power off: GPP_H17 -> 10ms -> GPP_A10
3. Warm reset: Power off -> 500ms -> Power on
Configure the GPIOs based on these requirements.
BUG=b:163100335
TEST=Build and boot Boten to OS. Ensure that the LTE module power
sequence requirements are met.
