mb/google/brox/var/jubilant: Add fw_config for WWAN Sar Sensor

The current WWAN(LTE) does not require any sar setting from RF team's
suggestion, and sar sensor will be removed from DVT schematic.
To reserve the extendibility, add the fw_config DB_1A_LTE_SAR:
field DB_USB 11 12
	option DB_1A		0 (None LTE)
	option DB_1A_LTE	1 (LTE without sar sensor)
	option DB_1A_LTE_SAR	2 (LTE with sar sensor)
end

Base on the fw_config to enable/disable related functions:
0)Disable WWAN and Sar if DB_USB = DB_1A
1)Enable WWAN and disable sar sensor if DB_USB = DB_1A_LTE
2)Enable WWAN and Sar sensor if DB_USB = DB_1A_LTE_SAR

BUG=b:375341992
TEST=Build and verify on jubilant by DB_USB= 0,1,and 2 of fw_config
     Check sar sensor and WWAN module from commands:
     ls -l /sys/bus/i2c/devices
     i2cdetect -y -r
     lsusb
