ec/quanta/it8518: correct ACPI battery data fed into ToString()
ToString() requires the input buffer data to be null-terminated, but the data returned by the EC is not, leading Windows to fail to report any battery data at all. Correct this by concatenating a null terminator (0x00) to the end of the buffer data before inputting to ToString() where needed TEST: boot Windows on google/stout, observe battery data reported correctly.
