i2c: gxp: fix build failure without CONFIG_I2C_SLAVE
The gxp_i2c_slave_irq_handler() is hidden in an #ifdef, but the caller uses an IS_ENABLED() check: drivers/i2c/busses/i2c-gxp.c: In function 'gxp_i2c_irq_handler': drivers/i2c/busses/i2c-gxp.c:467:29: error: implicit declaration of function 'gxp_i2c_slave_irq_handler'; did you mean 'gxp_i2c_irq_handler'? [-Werror=implicit-function-declaration] It has to consistently use one method or the other to avoid warnings, so move to IS_ENABLED() here for readability and build coverage, and move the #ifdef in linux/i2c.h to allow building it as dead code.
