drivers/intel/dptf: Correct UID for TBAT device
As per Intel Dynamic Tuning Spec revision 1.3.13, section 14.1.2 TBAT
_UID should match the _UID implemented for battery device ACPI object
for OS
_UID for TBAT is currently set to "TBAT" but should be 1.
Battery device is define at src/ec/google/chromeec/acpi/battery.asl
Setting _UID to 1 because right now ChromeOS is the only user
of DPTF driver
TEST: Build and boot brya0
