drivers/usbhost: Add a USB bluetooth driver.

This change adds support for the USB Transport Layer as described in the bluetooth spec. Isochronous endpoints are not yet supported. Because of limitations in the NuttX bluetooth stack, only one USB device can be used. This driver will only allow one USB dongle to use bluetooth. A Laird USB BT4.2 dongle (from Mouser) was used for testing: M/N BT851 1.0 1829, FCC ID:SQGBT850 lsusb: 04b4:f901 Cypress Semiconductor Corp. CYW20704A2 The following commands were used to test from the nsh prompt: bt bnep0 scan start bt bnep0 scan stop bt bnep0 scan get bt bnep0 info The Linux gatttool was used to connect over wireless. With the BDAddr found by "bt bnep0 info", start gatttool using: gatttool -b BDAddr -I Connect to the device using: connect Read the device name using the GAP device name UUID: char-read-uuid 2a00 Part of the response is: value: 41 70 61 63 68 65 20 4e 75 74 74 58 which is the string "Apache NuttX"
