[PATCH v3 1/5] iio: accel: mma9551/mma9553: Drop explicit ACPI match support

[Jonathan Cameron <jic23@kernel.org>]

From: Jonathan Cameron <Jonathan.Cameron@huawei.com>

The IDs look highly suspicious as they are just the part numbers in
capitals, so lets drop these if no one screams.

Note:
- MMA is registered PNP ID for Micromedia AG (not a part of Freescale)
- Googling doesn't show any results for such ACPI _HID to be present
  in the wild
