[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).
