ARM: imx: platform-imx-fb: modifies platform device name

Framebuffer platform device is now identified by a device id (imx1-fb or imx21-fb) instead of by driver name (imx-fb). Signed-off-by: Gwenhael Goavec-Merou <gwenhael.goavec-merou@armadeus.com> Signed-off-by: Shawn Guo <shawn.guo@linaro.org>

+ * DESCRIPTION: Parse a control method AML to scan for control methods that
+ *              need serialization due to the creation of named objects.
+ *
+ * NOTE: It is a bit of overkill to mark all such methods serialized, since
+ * there is only a problem if the method actually blocks during execution.
+ * A blocking operation is, for example, a Sleep() operation, or any access
+ * to an operation region. However, it is probably not possible to easily
+ * detect whether a method will block or not, so we simply mark all suspicious
+ * methods as serialized.
+ *
+ * NOTE2: This code is essentially a generic routine for parsing a single
+ * control method.
