[PATCH AUTOSEL 5.17 105/149] power: supply: axp288_fuel_gauge: Use acpi_quirk_skip_acpi_ac_and_battery()

[Sasha Levin <sashal@kernel.org>]

From: Hans de Goede <hdegoede@redhat.com>

[ Upstream commit da365db704d290fb4dc4cdbd41f60b0ecec1cc03 ]

Normally the native AXP288 fg/charger drivers are preferred but one some
devices the ACPI drivers should be used instead.

The ACPI battery/ac drivers use the acpi_quirk_skip_acpi_ac_and_battery()
helper to determine if they should skip loading because native fuel-gauge/
charger drivers like the AXP288 drivers will be used.

The new acpi_quirk_skip_acpi_ac_and_battery() helper includes a list of
exceptions for boards where the ACPI drivers should be used instead.

Use this new helper to avoid loading on such boards. Note this requires
adding a Kconfig dependency on ACPI, this is not a problem because ACPI
should be enabled on all boards with an AXP288 PMIC anyways.
