Support per-device Low Power Mode configuration

Broadcom's Bluedroid's libbt-vendor implementation provides a set of configurable values for the sleep_mode initialization. For example, some devices have an active IRQ polarity set to 0 instead of the default 1. In order to properly configure the BT chip, this patch exposes a set of known LPM configurations choosable with LPM_DEVICE macro.
