BQ274XX Sensors Driver - Fails with CONFIG_BQ274XX_LAZY_CONFIGURE

[ballardr]

Describe the bug
When using the BQ274XX Sensors driver, there is a kconfig CONFIG_BQ274XX_LAZY_CONFIGURE that allows the device not to be imitated until it's first use. I use this as the communication pull ups in the BQ274XX are disabled on boot (enabled in boot process however).

If CONFIG_BQ274XX_LAZY_CONFIGURE is set however, compilation fails as the following code references a bq274xx struct that doesn't exist. See lines 405-409 of ${zephyr}/drivers/sensor/bq274xx/bq274xx.c

#ifdef CONFIG_BQ274XX_LAZY_CONFIGURE
	bq274xx->lazy_loaded = false;
#else
	status = bq274xx_gauge_configure(dev);
#endif

To Reproduce
Steps to reproduce the behavior:
I'd have thought you should be able to compile the sample ${zephyr}/samples/sensor/bq274xx/ but with the CONFIG_BQ274XX_LAZY_CONFIGURE set to get the error
4. See error

Expected behavior
CONFIG_BQ274XX_LAZY_CONFIGURE should allow the BQ274XX not to be imitated until it's first use

Impact
Compilation failure

From looking at elsewhere in file, the code above should be similar to:

#ifdef CONFIG_BQ274XX_LAZY_CONFIGURE
	struct bq274xx_data *bq274xx = dev->data;
	bq274xx->lazy_loaded = false;
#else
	status = bq274xx_gauge_configure(dev);
#endif
