5.4-stable review patch. If anyone has any objections, please let me know.

commit 609bc31eca06c7408e6860d8b46311ebe45c1fef upstream.
The inclinometer channels were previously defined with 14 realbits. However, the ADIS16201 datasheet states the resolution for these output channels is 12 bits (Page 14, text description; Page 15, table 7).
Correct the realbits value to 12 to accurately reflect the hardware.
