mb/google/dedede/var/metaknight: Add LTE power on/off sequence
LTE module used in metaknight has a specific power on/off sequence. GPIOs related to power sequence 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: GPP_A10 keeps high, GPP_H17 goes low at least 2ms Configure the GPIOs based on these requirements.
BUG=b:173671094 TEST=Build and boot Metaknight to OS. Ensure that the LTE module power sequence requirements are met.
