Stefan Roese a8eeaf2f7a cmd_led: Extend led command to support blinking and more leds
This patch extends the U-Boot "led" command to support automatic blinking
by setting a blink frequency in milliseconds. Additionally the number of
supported LEDs is increased to 6 (0...5).

This will be used by the PCA9551 LED driver.

* PCBoot, a status LED is blinking. As soon as a valid BOOTP reply
* message has been received, the LED is turned off. The Linux
* kernel, once it is running, will start blinking the LED again,
* with another frequency.
