hauke 32dec7075a ocf-linux: version bump to 20110720 
Fixes problem with TFM allocation in cryptosoft.c


Signed-off-by: Philip Prindeville <philipp@redfish-solutions.com>

Hauke:
 * remove ubsec_ssb package and take it from ocf-linux
 * use patches from ocf-linux package
 * refresh all patches
 * readd some build fixes for OpenWrt.
 * readd CRYPTO_MANAGER dependency
