ZRAM is a memory compression method that used for anon swap out/in,
it could help system reclaim more free memory when the applications
have consumed too much memory. So we introduce the ZRAM by kernel
modules, user could insmod it as needed.

CONFIG_BLK_DEV_RAM=y will create /dev/ram* by default which is unneeded,
just make it a module, ram block devices can still be created with
modprobe.

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
