Subject: [PATCH 5/7] power: supply: rt9455: skip 'struct acpi_device_id' when !CONFIG_ACPI

Since ACPI_PTR() is used to NULLify the value when !CONFIG_ACPI, the
struct acpi_device_id becomes unused:

  drivers/power/supply/rt9455_charger.c:1734:36: warning:
    'rt9455_i2c_acpi_match' defined but not used [-Wunused-const-variable=]
