ravb: Group descriptor types used in Rx ring

[ Upstream commit 4123c3fbf8632e5c553222bf1c10b3a3e0a8dc06 ] The Rx ring can either be made up of normal or extended descriptors, not a mix of the two at the same time. Make this explicit by grouping the two variables in a rx_ring union. The extension of the storage for more than one queue of normal descriptors from a single to NUM_RX_QUEUE queues have no practical effect. But aids in making the code readable as the code that uses it already piggyback on other members of struct ravb_private that are arrays of max length NUM_RX_QUEUE, e.g. rx_desc_dma. This will also make further refactoring easier. While at it, rename the normal descriptor Rx ring to make it clear it's not strictly related to the GbEthernet E-MAC IP found in RZ/G2L, normal descriptors could be used on R-Car SoCs too.

Hm, I doubt this patch is actually necessary here...
