In mmotm-2009-0410, this patch causes build errors when GPIOLIB is not enabled
since GPIO_CS553X uses gpiolib functions & struct fields:

drivers/gpio/cs553x-gpio.c:23: error: field 'chip' has incomplete type
drivers/gpio/cs553x-gpio.c:150: error: field name not in record or union initializer
drivers/gpio/cs553x-gpio.c:150: error: (near initialization for 'cs553x_gpio_chip.chip')
drivers/gpio/cs553x-gpio.c:151: error: field name not in record or union initializer

drivers/gpio/cs553x-gpio.c:153: error: field name not in record or union initializer
drivers/gpio/cs553x-gpio.c:153: error: (near initialization for 'cs553x_gpio_chip.chip')

drivers/gpio/cs553x-gpio.c:160: error: (near initialization for 'cs553x_gpio_chip.chip')
drivers/gpio/cs553x-gpio.c:197: error: implicit declaration of function 'gpiochip_add'
drivers/gpio/cs553x-gpio.c:216: error: implicit declaration of function 'gpiochip_remove'


One possible patch is also to select GPIOLIB above in the OLPC config block.
