[PATCH v2] ARM: imx: use IS_ENABLED() instead of checking for built-in or module

From: Javier Martinez Canillas
Date: Mon Aug 29 2016 - 06:12:21 EST


The IS_ENABLED() macro checks if a Kconfig symbol has been enabled either
built-in or as a module, use that macro instead of open coding the same.

Using the macro makes the code more readable by helping abstract away some
of the Kconfig built-in and module enable details.

Changes in v2:
- Remove duplicated Signed-off-by tag.
