Subject: Input: sis-i2c - select CONFIG_CRC_ITU_T

The newly added sis_i2c driver fails to link without the CRC_ITU_T
driver enabled:

drivers/input/touchscreen/sis_i2c.o: In function `sis_ts_irq_handler':
sis_i2c.c:(.text+0xc0): undefined reference to `crc_itu_t'

This adds a Kconfig select statement.
