[ARM] 5288/1: [AT91] Remove SMC configuration from devices.c files
In at91_add_device_nand(), do not configure the Static Memory controller with specific timing values. The *_devices.c files are board independent, and the SMC timing values are specific to the NAND devices that are installed on the board. The board-specific files are now responsible for configuring the Static Memory controller (if the don't want to leave it up to a bootloader).
