Subject: [PATCHv2] lis3lv02d: add axes knowledge of HP Pavilion dv5 models

Add support for HP Pavilion dv5.

Since Intel-based models have an inverted x axis, while AMD-based models
have an inverted y axis, we introduce a new macro that special-cases
axis orientation based on two DMI entries: HP dv5 axis configuration is
then based on both the PRODUCT and BOARD name.

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

This is a replacement for the
lis3lv02d-add-axes-knowledge-of-hp-pavilion-dv5-models.patch currently
on -mm.

Palatis Tseng confirmed that this fixes the sensor orientation for him, too.
