[PATCH] Bluetooth: NXP: select CONFIG_CRC8

[PATCH] Bluetooth: NXP: select CONFIG_CRC8

[Arnd Bergmann]

From: Arnd Bergmann <arnd@arndb.de>

The driver needs both CRC32 and CRC8 to link correctly:

ld.lld: error: undefined symbol: crc8_populate_msb
>>> referenced by btnxpuart.c
>>>               drivers/bluetooth/btnxpuart.o:(nxp_serdev_probe) in archive vmlinux.a
ld.lld: error: undefined symbol: crc8
>>> referenced by btnxpuart.c
>>>               drivers/bluetooth/btnxpuart.o:(nxp_send_ack) in archive vmlinux.a

Fixes: 3e662aa4453a ("Bluetooth: NXP: Add protocol support for NXP Bluetooth chipsets")

Right. ...I should have realized this was missing too when I noticed 
select CRC32 wasn't there.
