Jonathan Cameron 3b63f5e8f7 iio: accel: bmc150: Drop ACPI_PTR()
In general the complexity of avoiding maybe unused variable warnings is
not worth dealing with for the small amount of data saved. In thie
case, the i2c driver does include some other code under a CONFIG_ACPI
guard but remove the ACPI_PTR() usage anyway to bring keep it inline
with the spi driver.

Drop include of linux/acpi.h in the spi driver that doesn't need
it as struct acpi_device_id is defined in mod_devicetable.h which
is already included.
