Subject: [PATCH] lis3lv02d: add axes knowledge of HP Pavilion dv5 models

Add support for HP Pavlion dv5 models, whose sensor has an inverted x
axis.

Signed-off-by: Giuseppe Bilotta <giuseppe.bilotta@...il.com>

My HP Pavilion dv5 has an inverted x axis of the accelerometer, so this
patch marks the inversion for all the dv5. I can include the full
dmidecode output if this is deemed necessary.

With the laptop standing still on my desk jstest reports X and Y values
fluctuating from -8k to +8k (more or less). I assume this is normal?
