When building with a version of GCC prior to 8.x, there is an error
around non-constant initializer elements:
drivers/power/supply/bq24190_charger.c:1978:16: error: initializer element is not constant
.vbus_desc = bq24190_vbus_desc,
^~~~~~~~~~~~~~~~~

Clang versions prior to 17.x show a similar error:
drivers/power/supply/bq24190_charger.c:1978:16: error: initializer element is not a compile-time constant
.vbus_desc = bq24190_vbus_desc,
^~~~~~~~~~~~~~~~~
1 error generated.
Newer compilers have decided to accept these structures as compile time
constants as an extension. To resolve this issue for all supported
compilers, change the vbus_desc member in 'struct bq24190_chip_info' to
a pointer, as it is only ever passed by reference anyways, and adjust
the assignments accordingly.
