Subject[PATCH] drivers: input: Include appropriate header file in cyttsp_i2c_common.c
This patch includes appropriate header file cyttsp4_core.h in
touchscreen/cyttsp_i2c_common.c because functions
cyttsp_i2c_read_block_data() and cyttsp_i2c_write_block_data()
have their prototype declaration in cyttsp4_core.h.

Thus, it also eliminates the following warning in cyttsp_i2c_common.c:
drivers/input/touchscreen/cyttsp_i2c_common.c:34:5: warning: no previous prototype for ‘cyttsp_i2c_read_block_data’ [-Wmissing-prototypes]
drivers/input/touchscreen/cyttsp_i2c_common.c:64:5: warning: no previous prototype for ‘cyttsp_i2c_write_block_data’ [-Wmissing-prototypes]
