The linux/cec.h header file contains empty inline definitions for
a subset of the API for the case in which CEC is not enabled,
however we have driver that call other functions as well:
drivers/media/i2c/adv7604.c: In function 'adv76xx_cec_tx_raw_status':
drivers/media/i2c/adv7604.c:1956:3: error: implicit declaration of function 'cec_transmit_done' [-Werror=implicit-function-declaration]
drivers/media/i2c/adv7604.c: In function 'adv76xx_cec_isr':
drivers/media/i2c/adv7604.c:2012:4: error: implicit declaration of function 'cec_received_msg' [-Werror=implicit-function-declaration]
drivers/media/i2c/adv7604.c: In function 'adv76xx_probe':
drivers/media/i2c/adv7604.c:3482:20: error: implicit declaration of function 'cec_allocate_adapter' [-Werror=implicit-function-declaration]
This adds stubs for the remaining interfaces as well.
