Subject: [PATCH v1 5/8] iio: accel: adxl345: Add ACPI HID table

From: Kai-Heng Feng <kai.heng.feng@...onical.com>

x86 boards may use ACPI HID "ADS0345" for adxl345 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.

Since ACPI device may not match to any I2C ID, use the name and type
directly from ACPI ID table in absence of I2C ID.
