defconfig: lahaina: enable QTI battery debug driver

QTI battery debug driver helps to get logs and debug information
by communicating with charger firmware (CHGFW) running on the
remote subsystem (e.g. DSP) over PMIC Glink. Currently, it
supports getting the device context dump of battery gauging
software which is part of CHGFW.
