[PATCH] greybus: BeaglePlay driver needs CRC_CCITT

[Randy Dunlap <rdunlap@infradead.org>]

The gb-beagleplay driver uses crc_ccitt(), so it should select
CRC_CCITT to make sure that the function is available.

Fixes these build errors:

s390-linux-ld: drivers/greybus/gb-beagleplay.o: in function `hdlc_append_tx_u8':
gb-beagleplay.c:(.text+0x2c0): undefined reference to `crc_ccitt'
s390-linux-ld: drivers/greybus/gb-beagleplay.o: in function `hdlc_rx_frame':
gb-beagleplay.c:(.text+0x6a0): undefined reference to `crc_ccitt'

Fixes: ec558bbfea67 ("greybus: Add BeaglePlay Linux Driver")
