crypto: qat - set COMPRESSION capability for DH895XCC
[ Upstream commit 0eaa51543273fd0f4ba9bea83638f7033436e5eb ]
The capability detection logic clears bits for the features that are
disabled in a certain SKU. For example, if the bit associate to
compression is not present in the LEGFUSE register, the correspondent
bit is cleared in the capability mask.
This change adds the compression capability to the mask as this was
missing in the commit that enhanced the capability detection logic.
