i.MX35 clock support: remove automotive path
It is no longer present in newer cores. Unfortunately Freescale decided to put the bit which decides between automotive clock path and consumer clock path in the automotive clock path direction. With current code we cannot detect the core revision, so just remove automotive path completely. Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>
