Subject: [PATCH] Rename RH_DISABLE_DEPRECATED to RHEL_DIFFERENCES

The intent of RH_DISABLE_DEPRECATED was to provide Red Hat a
simple way to disable drivers it did not want to support in RHEL.

As the config option was applied to more drivers and infra, it became
clear the option was being used for not only deprecating drivers (which
implied limited support) to disabling drivers (implying no support).

Using the word 'deprecated' seemed confusing in the second scenario.
Rename the option to be more generic and useable across more parts
of the kernel tree.

The new wording is RHEL_DIFFERENCES.

Upstream Status: RHEL only
