ANDROID: GKI: update the abi .xml file

Commit 15b78a8e ("hex2bin: make the function hex_to_bin
constant-time") in 5.4.192 changed the signature of the hex_to_bin()
function to fix a key leak attack vector.  This is not an abi break as
older modules that use the function will still work properly, and the
CRC is preserved, but this resolves any issues going forward as well.
