Bluetooth: btusb: Add a new QCA_ROME device (0cf3:e500)

Browse Source 
This patch adds the 0cf3:e500 Bluetooth device (from a QCA9377 board) as a
QCA_ROME device.  It appears to be functionally identical to another device
ID, also from a QCA9377 board, which was previously marked as QCA_ROME in
0a03f98b98
("Bluetooth: Add a new 04ca:3015 QCA_ROME device").

Without this patch, the WiFi side of the QCA9377 board is slow or unusable
when the Bluetooth side is in use.

See https://askubuntu.com/a/1137852 for another report of QCA_ROME fixing
this issue for this device ID.
