ARM: at91: remove at91sam9261/at91sam9g10 legacy board support
Remove legacy support for at91sam9261/at91sam9g10 boards. This include board files removal plus all legacy code for non DT boards support. Use the Device Tree for running this board with newer kernels. Signed-off-by: Nicolas Ferre <nicolas.ferre@atmel.com>
