i2c: Provide a stub for i2c_detect_slave_mode()
Drivers would like to call i2c_detect_slave_mode() even if !I2C_SLAVE.
Give them what they want to,
Otherwise kernel will not compile:
drivers/i2c/busses/i2c-designware-platdrv.c: In function ‘dw_i2c_plat_probe’:
drivers/i2c/busses/i2c-designware-platdrv.c:331:6: error: implicit declaration of function ‘i2c_detect_slave_mode’ [-Werror=implicit-function-declaration]
if (i2c_detect_slave_mode(&pdev->dev))
^~~~~~~~~~~~~~~~~~~~~
cc1: some warnings being treated as errors
Fixes: 6e38cf3b4421 ("i2c: designware: Let slave adapter support be optional")
