driver/battery: add command to fake battery temperature
The 'batttempfake' command allows overriding the battery temperature
reading, to test scenarios where the battery temperature affects the
charging operations.
BUG=None
BRANCH=None
TEST=Set GBB flags to disable software sync and disable rollback checks
$ make -j BOARD=kohaku
$ ./util/flash_ec --board=kohaku
When the system reboots, open the EC console and execute the commands:
> help batttempfake
Usage: batttempfake temperature (-1 = use real temperature)
Set fake battery temperature in deciKelvin (2731 = 273.1 K = 0 deg C)
> batttempfake 2731
Fake batt temperature 273.1 K
> battery
...
Temp: 0x0aab = 273.1 K (0.0 C)
...
> batttempfake -1
> battery
...
Temp: 0x0bc9 = 301.7 K (28.6 C)
...
