Subject: [PATCH v2] Input: adxl34x: Add ACPI HID table

x86 boards may use ACPI HID "ADS0345" for adxl34x device.

Analog replied:
"ADS034X is not a valid PNP ID. ADS0345 would be.
I'm not aware that this ID is already taken.
Feel free to submit a mainline Linux input mailing list patch."

So add an ACPI match table for that accordingly.

v2:
 - Drop ACPI_PTR()
 - Drop redundant empty line and comma
 - Add info from vendor
