Bluetooth: btbcm: Introduce generic Broadcom Bluetooth support The majority of Broadcom Bluetooth vendor commands are shared between USB and UART transports.

Bluetooth: btbcm: Fix sleep mode struct ordering According to the documentation for Laird SD40 radio modules (which use the BCM4329 chipset), the order of the Enable_BREAK_To_Host and Pulsed_HOST_WAKE parameters in the sleep mode struct is reversed vis-à-vis our struct declaration. See page 46 of this PDF: http://cdn.lairdtech.com/home/brandworld/files/Application%20Note%20-%2040%20Series%20Bluetooth.pdf The documentation is dated Oct 2015, so fairly recent, making it appear more likely that the documentation is correct and our code is wrong. Amend our code to be in congruence with the documentation.
