mb/google/nissa: Simplify LTE GPIO config using pad-based overrides

Currently, to enable/disable LTE based on fw_config on nissa, we have
two sets of GPIOs: lte_enable_pads and lte_disable_pads. This was to
prevent the SAR interrupt pin GPP_H19 from floating for the short period
of time between enabling it in gpio.c and disabling it in fw_config.c
(see CB:64270 for more details).

With the new pad-based GPIO overrides (CB:64712), this is no longer an
issue since the gpio.c and fw_config.c overrides are applied at the same
time. So simplify the LTE GPIO configuration by enabling all the LTE
pins in the variant gpio.c, then disabling them in fw_config.c if
needed.

BUG=b:231690996
TEST=LTE still works on nivviks
