power: supply: axp288_charger: Use acpi_quirk_skip_acpi_ac_and_battery()
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.
