drivers: sensors: lis2dh: added full high-pass filter capabilities

The lis2dh driver has the ability to enable the hp filter.
However it was only possible to set the first 2 bits of the hp register.
These bits indicate wether the hp filter is enabled for the interrupts.
This commit moves lis2dh_acc_hp_filter_set to lis2dh.
 It also removes the mask so that all bits are able to be set.
