Update anti-DG.

I'll switch to a code patch later; I feel patching data for this seems error-prone.

 # Anti-anti-downgrade fix.
 
+# How this works: The FIRM has a list of titleids in it to verify
+# that downgrade is not performed. This is verified in a function
+# that loops through each of the titleids on an install.
+
+# The downgrade check ends when a zero is encountered. Luma patches
+# this check by zeroing the first titleid.
+
+# The "first" revision of this patched the code for said check to never 
+# execute. Sadly, the code is VERY different in 11.2...
