From: Karthikeyan Gopal <karthikeyan.gopal@intel.com>

The LZS and RAND features are no longer available on QAT.
Remove the definition of bit 6 (LZS) and bit 7 (RAND) in the enum that
represents the capabilities and replace them with a comment mentioning
that those bits are reserved.
Those bits shall not be used in future.
