Subject: [PATCH 4.4 231/312] power: bq27xxx_battery: Fix bq27541 AveragePower register address

From: Liu Xiang <liu.xiang6@....com.cn>

commit 265b60497a57da56a4be7d5c72983ae89dc0765e upstream.

Currently in bq27541 driver, the average power register address is
incorrectly set to 0x76, which would result in an error:
bq27xxx-battery 2-0055: error reading average power register  10: -11
According to the bq27541 datasheet, fix this problem by setting
the average power register address to 0x24.
