mlx4_core: Read extended capabilities into the flags field
Query another dword containing up to 32 extended device capabilities
and merge it into struct mlx4_caps.flags. Update the code that
handles the current extended device capabilities (e.g UDP RSS, WoL,
vep steering, etc) to use the extended device cap flags field instead
of a field per extended capability. Initial patch done by Eli Cohen
<eli@mellanox.co.il>.
