Fuhai Wang 1e236c7732 ampere/led: Add Altra LED driver 
Add Altra LED driver to control NVME LED.

This driver support control LED via SPCI interface on Altra system.
Currently, it is 2-LEDs system(Activity LED, Status LED). Activity
LED is completely controlled by hardware. Status LED is controlled
by this driver.
There are 4 stages of Status LED:
    - ON
    - OFF
    - Locate(blink at 1Hz)
    - Rebuild(blink at 4Hz)

Example:
To On, Off the LED on slot 9:
    1. Write the seg:bus_number corresponding to LED on slot 9 to
       altra:led
         echo 000b:03 > /sys/class/leds/altra:led/address
    2. Write 1 to brightness attr to ON, 0 to brightness attr to OFF
         echo 1 > /sys/class/leds/altra:led/brightness
         echo 0 > /sys/class/leds/altra:led/brightness
To blink the LED on slot 9:
    1. Write the seg:bus_number corresponding to LED on slot 9 to
       altra:led
         echo 000b:03 > /sys/class/leds/altra:led/address
    2. Write 1 to blink attr to select Locate(blink 1Hz), or 4 to
       blink attr to select Rebuild(blink 4Hz)
         echo 1 > /sys/class/leds/altra:led/blink
         echo 4 > /sys/class/leds/altra:led/blink
    3. Write 1 to shot attr to execute blink
         echo 1 > /sys/class/leds/altra:led/shot
