iio: accel: bmc150: Refactor bmc150_apply_acpi_orientation()

Factor the BOSC0200 ACPI HID handling out into a new
bmc150_apply_bosc0200_acpi_orientation() function and make
bmc150_apply_acpi_orientation() call that when dealing with
a BOSC0200 ACPI device (and make it return false otherwise).

This is a preparation patch for adding special handling for other
ACPI HIDs (the "DUAL250E" HID).
