[PATCH net-next 2/2] net: macb: add QBV capability to 4 compatibles

["Théo Lebrun" <theo.lebrun@bootlin.com>]

Add MACB_CAPS_QBV to four compatibles. Tested on EyeQ5 hardware.
The other ones are not tested. Datasheets indicate support.

   Compatible             | Datasheet
   -----------------------+------------------------
   mobileye,eyeq5-gem     | Not public
   microchip,mpfs-macb    | Public header files [0]
   microchip,sam9x7-gem   | DS60001813 [1]
   microchip,sama7d65-gem | DS60001851 [2]

For the latter two, upstream devicetrees and bindings know about the
compatible but the driver only used their "parent" compatible
microchip,sama7g5-gem. Therefore add match data for those two. Instead
of duplicating the long caps list, store it in a define which gets
called three times.
