ramdump: write compressed data [2/2]

Browse Source 
PD#SWPL-6193

Problem:
ramdump need write compressed data to persist storage device.
But if we write it under uboot, it may cause journal and block
bitmap mismatch due to different version of file system. This
caused kernel panic after ramdump finished.

Solution:
Write compressed data under kernel.
This change also removed some extern function of ramdump since
we use sticky register to store ramdump information.

Verify:
p212
