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.
