[ Upstream commit d33a23b0532d5d1b5b700e8641661261e7dbef61 ]
The bitreverse helper is almost always built into the kernel, but in a rare randconfig build it is possible to hit a case in which it is a loadable module while the atmel-i2c driver is built-in:
arm-linux-gnueabi-ld: drivers/crypto/atmel-i2c.o: in function `atmel_i2c_checksum': atmel-i2c.c:(.text+0xa0): undefined reference to `byte_rev_table'
Add one more 'select' statement to prevent this.
