Bluetooth: hci_bcm: Limit bcm43455 baudrate to 2000000
Like the bcm43430a0 the bcm43455 BT does not support the 0xfc45 command
to set the UART clock to 48 MHz and because of this it does not work
at 4000000 baud.
These chips are found on ACPI/x86 devices where the operating baudrate
does not come from the firmware but is hardcoded at 4000000, which does
not work.
Make the driver_data for the "BCM2EA4" ACPI HID which is used for
the bcm43455 BT point to bcm43430_device_data which limits the baudrate
to 2000000.
