Peter Senna Tschudin 7b34be71db [media] use IS_ENABLED() macro
This patch introduces the use of IS_ENABLED() macro. For example,
replacing:
 #if defined(CONFIG_I2C) || (defined(CONFIG_I2C_MODULE) && defined(MODULE))
with:
 #if IS_ENABLED(CONFIG_I2C)
All changes made by this patch respect the same replacement pattern.
