[PATCH 1/5] crc16-ccitt: Rename file with CRC-16-CCITT implementation to crc16-ccitt.c

["Pali Rohár" <pali@kernel.org>]

U-Boot CRC-16 implementation uses polynomial x^16 + x^12 + x^5 + 1 which is
not standard CRC-16 algorithm, but it is known as CRC-16-CCITT. Rename file
crc16.c to crc16-ccitt.c to reduce confusion.
