[ARM] 5056/1: [AT91] Cleanup YL9200 board file
Cleanup the YL9200 board-support file. Other things fixed are: - Use new-style UART initialization - Register all LEDs as gpio_leds. - NOR Flash error noted in comments fixed by increasing YL9200_FLASH_SIZE - The only I2C device is the AT24C eeprom. - Setup of NWAIT pin and programming of SMC controller for the LCD/VGA. - Configure touchscreen interrupt pin. Also adding the board to the KConfig and Makefile. Signed-off-by: Andrew Victor <linux@maxim.org.za> Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>
