Subject: [PATCH 1305/1350] dts: bcm2712d0: Add non-d0 vc6 compatible string

Although the VC4/VC6 driver requires a special compatible string for the
"d0" stepping, the removal of the old compatible string upsets Mesa.

Satisfy both requirements by adding the old "brcm,bcm2712-vc6" string
as a fallback.
