Remove PPC support for IDE.
Based on a suggestion from S. Hauer, we don't currently need any IDE support, but we can always add it back later if we choose. There don't appear to be any other IDE-related source files in the tree. Signed-off-by: Robert P. J. Day <rpjday@crashcourse.ca> Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>
